Question

A block with mass of 5.97 kg is attached to a horizontal spring with spring constant k = 4.02 102 N/m. The surface the block rests upon is frictionless. The block is pulled out to xi = 0.0480 m and released. (a) Find the speed of the block at the equilibrium point. Answer 0.3938m/s (b) Find the speed when x = 0.027 m. (c) Repeat part (a) if friction acts on the block, with coefficient μk = 0.130.
