Question

A NASA astronaut hits a golf ball on the Moon. Which of thefollowing quantities, if any, remain constant as the ball travelsthrough the lunar vacuum? a) speed b) acceleration c) velocity d) horizontal component of velocity e) vertical component of velocity *please let me know why whatever answer is correct!

Explanation / Answer

first, hitting a golf ball on the moon is similar to hitting a golfball on earth, only the acceleration due to gravity is different(about 1/6 of its value on earth). so on earth, the horizontal component of velocity would be aconstant, because there is no acceleration. The vertical component of acceleration is a constant as well(constant acceleration due to gravity), and since there is nohorizontal component of acceleration, the magnitude of the totalacceleration should also be considered a constant. total speed, total velocity, and vertical component of velocity arenot constant. so the answer is (D) and (B)
