On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 25 m/s at an angle 30º above the horizontal. a. How long was the ball in flight? b. How far did it travel? c. Ignoring air resistance, how much farther would it travel on the moon than on earth?

Three moles of an ideal gas undergo a reversible isothermal compression at 20.0° C. During this compression,
1900 J of work is done on the gas.

5.97 Block A, with weight
3w, slides down an inclined plane
S of slope angle 36.9° at a constant
speed while plank B, with weight
w, rests on top of A. The plank
is attached by a cord to the wall
(Fig. P5.97). (a) Draw a diagram
of all the forces acting on block
A. (b) If the coefficient of kinetic
friction is the same between A and
B and between S and A, determine
