Question
(14%) Problem 4: On the moon the acceleration due to gravity is l/6 of Earth's. A ball is thrown straight up on the moon and it takes t = 26 s to return to the surface ©theexpertta.com 25% Part (a) What is the numeric value for the magnitude of the free fall acceleration on the moon, gmoon in m/s 25% Part (b) Write an expression for the maximum height achieved by the ball on the moon, hm, in terms of the gravitational acceleration on earth, g, and the time, t.

a) gmoon = 9.81/6 = 1.64 m/s2
b) hm= (1/2)gmoont2 = (1/12)gt2
c) here, time to reach to maximum height, t= 26/2 s = 13 s
hm= (1/12)*9.81*132 m = 138.16 m
d) hm= 138.16 m
he= (1/2)gt2 = 0.5*9.81*132 = 829 m
difference = 829-138 = 691 m
