A 1.50-kg object is held 1.20 m above a relaxed mass less vertical spring with a force constant of 320 N/m. The object is dropped onto the spring. (a) How far does it compress the spring? (b) What If? How far does it compress the spring if the same experiment is performed on the Moon, where g = 1.63 m/s2? (c) What If? Repeat part (a), but this time assume a constant air-resistance force of 0.700 N acts on the object during its motion.
