Q1. A 1.50 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 it compress the spring?

(b) How far does it compress the spring if same experiment is performed on the moon, where g = 1.63 m/s2?

(c) Repeat part (a), but now assume that a constant air-resistance force of 0.700 N acts on the object during its motion.

Q2. The flywheel of an engine has a moment of inertia 3.00 {rm kg} cdot {rm m} ^ {2} about its rotation axis. What is its final kinetic energy?
