[SOLVED] Object Dropped on a Spring 1. The problem statement, all variables and given/known data A 1.30 kg object is held 1.20 m above a relaxed, massless vertical spring with a force constant of 310 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? ________m (b) How far does the object compress the spring if the same experiment is performed on the moon, where g = 1.63 m/s2? _________m (c) Repeat part (a), but now assume that a constant air-resistance force of 0.700 N acts on the object during its motion. _________m 2. Relevant equations 3. The attempt at a solution I found the answers for part a and b to be .357832 and .1351 respectivly, but I'm not sure on how to solve part c which adds in the friction of air.
