A1.60-kg object is held 1.05 m above a relaxed, massless vertical spring with a force constant of 330 n/m. the object is dropped onto the spring.
(a) how far does the object compress the spring?
m
(b) repeat part (a), but this time assume a constant air-resistance force of 0.750 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
