Galileo does an experiment. He goes to the top of the leaning tower of pisa and drops a concrete ball and a wooden ball of equal size.The concrete ball has twice the mass of the wooden ball. How do the kinetic energies of the balls compare as they reach the ground? a) The wooden one has four times as much kinetic energy as the other does. b) The wooden one has twice as much kinetic energy as the other does. c) The wooden one has the same kinetic energy as the other does. d) The wooden one has one fourth as much kinetic energy as the other does. e) The wooden one has one half as much kinetic energy as the other does.

A block is placed on top of a vertical spring, and the spring compresses. Figure P8.24 depicts a moment in time when the spring is compressed by an amount h. a. To calculate the change in the gravitational and elastic potential energies, what must be included in the system? b. Find an expression for the change in the systems potential energy in terms of the parameters shown in Figure P8.24. c. If m = 0.865 kg and k = 125 N/m, find the change in the systems potential energy when the blocks displacement is h = 0.0650 m, relative to its initial position. FIGURE P8.24
A boy starts at rest and slides down a frictionless slide as in Figure P5.64. The bottom of the track is a height h above the ground. The boy then leaves the track horizontally, striking the ground a distance d as shown. Using energy methods, determine the initial height H of the boy in terms of h and d. Figure P5.64
At the start of a basketball game, a referee tosses a basketball straight into the air by giving it some initial speed. After being given that speed, the ball reaches a maximum height of 4.25 m above where it started. Using conservation of energy, find a. the balls initial speed and b. the height of the ball when it has a speed of 2.5 m/s.
Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the bow back 50 cm and holds it in position with a force of 150 N. If the mass of the arrow is 50 g and the “spring” is massless, what is the speed of the arrow immediately after it leaves the bow?
Give an example of a situation in which there is a force and a displacement, but the force does no work. Explain why it does no work.
