1.) On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The
acceleration due to gravity on the moon is 1/6 of its
value on earth. Suppose he hits the ball with a
speed of 27 m/s at an angle 60 ° above the
horizontal.
A. How much farther did the ball travel on the moon than it would have on earth? B. for how much time was the ball in flight?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of
