CP ?Longitudinal Waves on a Spring. A long spring such as a Slinky™ is often used to demonstrate longitudinal waves. (a) Show that if a spring that obeys Hooke’s law has mass m, length L, and force constant k’, the speed of longitudinal waves on the spring is (see Section 16.2). (b) Evaluate v for a spring with m = 0.250 kg, L = 2.00 m, and k’ = 1.50 N/m.
