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 hits the ball with a speed of 21 m/s at an angle of 29° above the horizontal.
(a) How long was the ball in flight?
s

(b) How far did it travel?
m

(c) How much farther would it have traveled on the moon than on earth?
m

Need to draw it

danjs · Answer

Same as the projectile motion problem on earth, except use the acceleration of gravity as g/6  or 9.8/6  m/s^2,  it will travel farther and a longer time than earth.

i still dont know how to do it though
