An 80 kg object is dropped from rest from a height of 25 meters above the ground. Use the concept of energy conservation to find its speed when it is 10 meters above the ground.
(a) A ball is dropped from rest from an initial height h above the floor. It then bounces several times. Draw graphs the position y(e), velocity v, (e) and acceleration ay () of the ball for two complete bounces (hitting the ground t for py Ct) ay (t) (b) If the ball is released from rest at a height h the ground? 1.50 m above the floor, how fast is the ball moving when it reach (c) If the ball...
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 cylinder is dropped from rest at a height of 3.71 m above the ground. How long after it is release does the cylinder reach the ground (in seconds)? What is the instantaneous velocity of the cylinder just before it hits the ground (in m/s)?
A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)

On planet #5, a stone dropped from a height of 35.0 m above the ground will hit the ground at a speed of 37.5 m/s. What is the value of g for planet #5?
1. A particle of mass m and charge q is dropped from height of 3h above the ground. The particle starts from rest and its starting position is (x, y) (0,3h). At height 2h, the particle enters a uniform electric field of magnitude E pointing in the negative r direction. The magnitude of the force on the particle due to the electric field is qE. The particle exits the electric field at height h. A cup is placed at position...
A rock is dropped from a height of 110 meters above the ground. One second later, a ball is thrown vertically downward from the same height with an initial speed of 14 m/s. A. At what time after the ball if thrown are the two objects at the same height above the ground? B. What is the speed of the rock when the ball hits the ground?
