52. An object is dropped from a height of 75.0 m above ground level. (a) Determine the distance traveled during the first second. (b) Determine the final velocity at which the object hits the ground. (c) Determine the distance traveled during the last second of motion before hitting the ground.
1) An object is dropped from a height H. During the final second of its fall, traverses a distance of 46.5 m. What was H? m Submit
An object is dropped from rest from a height 7 × 10^6 m above the surface of the earth. If there is no air resistance, what is its speed when it strikes the earth? The acceleration of gravity is 9.81 m/s2 and the radius of the Earth is 6.37 × 10^6 m. Answer in units of km/s.

A 0.140-kg baseball is dropped from rest from a height of 2.20 m above the ground and experiences negligible air resistance as it falls. It rebounds to a height of 1.60 m. What change in the ball's momentum occurs as it rebounds from the ground? A) 0.117 kg ∙ m/s upwards B) 0.117 kg ∙ m/s downwards C) 1.70 kg ∙ m/s upwards D) 0.350 kg ∙ m/s upwards
Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.
A marble is dropped from rest (at a height of 10.0 m) into a large batch of chocolate chip cookie dough. The marble comes to rest in 0.87 seconds due to a constant upward force of 1.2 N supplied by the cookie dough. Gravity, of course, continues to act during the deceleration. Find the mass of the marble.
