A 1.80−kg object is held 1.15 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 0.650 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
