A 1.43 kg object is held 1.28 m above a relaxed, massless vertical spring with a force constant of 318 N/m. The object is dropped onto the spring.
(a) How far does the object compress the spring?
m
(b) Repeat part (a), but now assume that a constant air-resistance force of 0.768 N acts on the object during its motion.
m
(c) How far does the object compress the spring if the same experiment is performed on the moon, where g = 1.63 m/s2 and air resistance is neglected?
m
