A stone 0.44 kg mass is released from rest from a height of 29.4 m above the ground. Ignoring air resistance and letting the ground be the zero potential energy level,

  1. Determine the final kinetic energy of the stone using energy conservation principle only, not as a free fall.
  2. Determine the work done on the stone by gravity.

An object of mass 5 kg is released from rest 24525 m above the ground and allowed to fall under the influence of gravity. Assume the gravitational force is constant, with g=9.8 m/sec2 , and the force due to air resistance is proportional to the velocity of the object with proportionality constant k= 1 kg/sec. Approximate when (in seconds) the object will strike the ground.

An object of mass 120 kg is released from rest 480000 m above the ground and allowed to fall under the influence of gravity. Assume the gravitational force is constant, with g=9.8 m/sec2 , and the force due to air resistance is proportional to the velocity of the object with proportionality constant k= 3 kg/sec. Approximate the speed (in m/sec) of the object when it strikes the ground.

A 1-kg ball is released from a height of 6 m, and a 2-kg ball is released from a height of 3 m. Air resistance is negligible as they fall. Which of the following statements about these balls are correct? (There could be more than one correct choice.) Both balls will reach the ground with the same speed. As they reach the ground, the 1-kg ball will have more kinetic energy than the 2-kg ball because it was dropped from...

A ball of mass 2.25 kg is released from rest at height 5.29 m above the floor. It falls, hits the ground, and rebounds to height 3.19 m above the floor. Assume none of the losses are due to air friction. Find the impulse, in N-s, exerted by the floor on the ball. The sign of your answer will give the direction of the impulse.
