a boy throws a ball straight up into the air. it reaches its highest point after 4 seconds.how fast was the ball going when it left the boy's hand
Answer:
Explanation:
The most important thing to remember about parabolic motion in physics is that when an object reaches its max height, the velocity right there at the highest point is 0. Use this one-dimensional motion equation to solve this problem:
v = v₀ + at and filling in:
0 = v₀ + (-9.8)(4.0) **I put in 4.0 for time so we have more than just 1 sig fig here**
0 = v₀ - 39 and
-v₀ = -39 so
v₀ = 39 m/s

What would the final volume of 40 L of gas at 80 pascals be if the pressure increases to 130 pascals?
Answer:
Final volume, V2 = 24.62 L
Explanation:
Given the following data;
Initial volume = 40 L
Initial pressure = 80 Pa
Final pressure = 130 Pa
To find the final volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 80 * 40 = 130V_{2} [/tex]
[tex] 3200 = 130V_{2} [/tex]
[tex] V_{2} = \frac {3200}{130}[/tex]
[tex] V_{2} = 24.62 [/tex]
Final volume, V2 = 24.62 Liters
39. A dog runs on a waxed floor at an initial speed of 2 m/s. It slides to a stop with an
acceleration of -0.43 m/s2. How long does it take for the dog to stop?
Answer:
Explanation:
Use the one-dimensional equation
[tex]v_f=v_0+at[/tex] where vf is the final velocity of the dog, v0 is the initial velocity of the dog, a is the acceleration of the dog, and t is the time it takesto reach that final velocity. For us:
0 = 2 + -.43t and
-2 = -.43t so
t = 4.7 seconds

Why are earths rocks generally younger than earth itself.
Answer:
The reason why the rocks are more younger than Eart itself is because they come from processes like plate tectonics, volcanoes, and erosions that made up Earth's surface.
Answer:
The lack of impact craters and the age of most rocks on Earth in comparison to other bodies in the solar system can be attributed to processes such as volcanism, plate tectonics, and erosion that have reshaped Earth's surface, and this is why most of Earth's rocks are much younger than the Earth itself.
An eccentric inventor attempts to levitate by first placing a large negative charge on himself and then putting a large positive charge on the ceiling of his workshop. Instead, while attempting to place a large negative charge on himself, his clothes fly off. Explain.
Answer:
shirt is little attached to the body, it can come off and fly away
Explanation:
In electrostatics, charges of different signs attract and charges of the same sign repel.
In this case, when a negative charge is placed on it, both the inventor and the shirt are charged, therefore there is a repulsive force, also there is an attraction between the positive charge of the roof attracts the negative charge, such as the shirt. of weak the two forces not greater than the resistance of the walk.
As the shirt is little attached to the body, it can come off and fly away

(b) The distance of mass from mass A if there is no gravitational force acted on C
Answer:
(a) The force, acting on object 'C' is approximately 2.66972 × 10⁻¹⁰ Newtons
(b) The distance of 'C' from 'A', in the direction particle 'B' if there is no meters gravitational force acting on 'C' is appromimately 0.829 meters or 1.877 meters
Explanation:
The given parameters are;
The mass of particle, A, m₁ = 2 kg
The mass of particle, B, m₂ = 0.3 kg
The mass of particle, C, m₃ = 0.05 kg
The distance between particle 'A' and particle 'B', r₁ = 0.15 m
The distance between particle 'B' and particle 'C', r₂ = 0.05 m
(a) The gravitational force, 'F', is given as follows;
[tex]F =G \times \dfrac{m_{1} \times m_{2}}{r^{2}}[/tex]
Where;
F = The force between the two masses
G = The gravitation constant = 6.67430 × 10⁻¹¹ N·m²/kg²
m₁ = The mass of object 1
m₂ = The mass of object 2
If 'C' is placed at 0.05 m from 'B', we have;
F₂₃ = 6.67430 × 10⁻¹¹ × 0.05 × 0.3/(0.05²) ≈ 4.00458 × 10⁻¹⁰
The gravitational force between force between particle 'B' and particle 'C', F₂₃ = 4.00458 × 10⁻¹⁰ N (towards the right)
F₁₃ = 6.67430 × 10⁻¹¹ × 0.05 × 2/(0.1²) ≈ × 10⁻¹⁰
The gravitational force between force between particle 'A' and particle 'B', F₁₃ = 6.6743 × 10⁻¹⁰ N (towards the left)
The force, 'F', acting on object 'C' = F₁₃ - F₂₃
F = (6.6743 - 4.00458) × 10⁻¹⁰ = 2.66972 × 10⁻¹⁰ N
The force, acting on object 'C' ≈ 2.66972 × 10⁻¹⁰ N
(b), When there is no gravitational force acting on 'C', let the distance of 'C' from 'A' = x
We have;
F₂₃ = F₁₂
[tex]F_{23} =G \times \dfrac{m_{1} \times m_{2}}{r_1^{2}} = F_{13} =G \times \dfrac{m_{1} \times m_{3}}{r_2^{2}}[/tex]
By plugging in the values and removing like terms, we get;
[tex]\dfrac{0.3 \times 0.05}{(1.15 - x)^{2}} = \dfrac{2 \times 0.05}{x^2}[/tex]
(1.15 - x)² × 2 × 0.05 = 0.3 × 0.05 × x²
0.1·x² - 0.23·x + 1.3225 = 0.015·x²
0.1·x² - 0.23·x + 1.3225 - 0.015·x² = 0
0.085·x² - 0.23·x + 0.13225= 0
x = (0.23± √((-0.23)² - 4 × 0.085 × ( 0.13225)))/(2 × 0.085))
x ≈ 0.829, or x ≈ 1.877
Therefore, the distance of 'C' from 'A', if there is no gravitational force acting on 'C', x ≈ 0.829 m, or x = 1.877 m, in the direction of 'B'

what is the x component that of a vector that is defined 2.5m at 64 degree?
A) -2.2m
B) 1.1m
C) 2.2m
D) -1.1m
Answer:
Explanation:
This is a displacement vector since it is given in terms of a distance (meters, to be specific). The way you find the x-component is:
[tex]V_x=Vcos\theta[/tex] which means you multiply the magnitude (length) of the vector times the cos of the direction (the angle):
[tex]V_x=2.5cos(64)[/tex] to get
1.1 m, choice B.
Which statements below are true? Check all that apply. A. If motion starts and stops at the same location, then the displacement is zero. B. Distance measurements must include magnitude, unit, and direction. I c. Distance is always greater than or equal to the magnitude of the displacement D. Displacement can be fully described with a magnitude and a unit.
Answer:
A. If motion starts and stop at the same location, then the displacement is zero
C. Distance is always greater than or equal to the magnitude of the displacement
Explanation:
The displacement of a body is a vector quantity that gives the shortest (straight line) distance moved by an object in motion, from its initial position to its final position. The displacement can also be described as the final position relative to the initial position of an object, such that the displacement vector, 's', is given as follows;
[tex]s = x_f - x _i[/tex]
The displacement gives the direct length between two points, with regards to the direction of motion between the points. It can only be described by both the magnitude and the direction
Therefore, displacement can be positive (forward motion), negative (backward motion), or zero (where there is motion that stops at the starting point)
Therefore, a correct options is; If motion starts and stop at the same location, then the displacement is zero
Displacement, being a vector quantity will have both magnitude and direction
Distance, however, is a scalar quantity, it specifies only magnitude, but does not specify direction
Distance, describes the length of the path taken from one point to the other. Distance gives the total movement a body makes, without regards to the direction of the motion
Therefore, distance is always positive or zero (here only the object is stationary)
Therefore, a correct option is; Distance is always greater than or equal to the magnitude of the displacement
Therefore, the correct options are;
If motion starts and stop at the same location, then the displacement is zero
