A 1.60-kg object is held 1.40 m above a relaxed, massless vertical spring with a force constant of 305 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 0.600 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?

A block of mass m = 0.3kg, initially at rest, is dropped onto a massless spring a distance h below. The block becomes attached to the spring and compresses it by (delta)x= 0.2 m before momentarily stopping. The spring constant k = 98 N/m. Air resistance is negligible. What is the initial height h of block above the top of the relaxed spring?
