A 0.400 kg object is attached to a spring with a spring constant of 117 N/m. The other end of the spring is attached to a wall. The spring rests on a frictionless horizontal surface. A force is exerted on the spring, causing it to compress by a distance of 7.00 cm. a) What force is exerted on the spring? Show your work. b) How much work is done on the spring to compress it? Show your work. c) Once the force on the spring is released, the spring and object are set into simple harmonic motion. Assuming that there is no friction, and that the mass of the spring is negligible, what will the spring's speed be when the spring is passing the point of being compressed by only 2.00 cm? Show your work. d) Explain where maximum speed occurs and why. ( )
