Question

A 50 cm long spring with spring constant 282 N/m has a mass 1.5 kg attached to it, and it can oscillate on a horizontal table without any friction. When the spring is pulled so that its length is 57 cm, what is the magnitude of the restoring force (in newtons) exerted by the spring?

Answer 1

Answer:The magnitude of the restoring force exerted by the spring is 19.74 N. Notice the negative sign in the answer. It indicates that the force is in the opposite direction of the displacement, as required by Hooke's Law.
