Answer:
The statement is true.
Both gravity and centrifugal force act on the Moon which causes it get pulled towards Earth (gravity) and get "flung away" so it doesn't hit us (centrifugal force).
Answer:
So it will lift the mass by h = 17 m
Explanation:
As per energy conservation we know that

here we know that


now we have


so work done by the engine is 250 J
now we have



F = (mass)(acceleration) = ma
m = 0.2 kg
Vi = 32 m/s
t = 0.5 s
Vf = 0 m/s (since it was put to stop)
a=(Vf-Vi)/t
a=(0-32)/0.5
a = 64 m/s^2 (decelerating)
F = ma = (0.2 kg)(64 m/s^2)
F = 12.8 N
