Question

A 26 lb cylindrical collar is released from rest at 14" above spring and drops onto the spring.

Calculate the speed v of the cylinder when the spring has been compressed 1.5 in.
k=234 lb/in

Answer 1

initial potential energy = m g h

energy of motion and compression = (1/2) m v^2 + (1/2) k x^2

Transform units into kg, m, s, N, J
