A block with mass of 4.52 kg is attached to a horizontal spring with spring constant k = 3.59 102 N/m, as shown in the figure. The surface the block rests upon is frictionless. The block is pulled out to xi = 0.0520 m and released.
(a) Find the speed of the block at the equilibrium point.
m/s
(b) Find the speed when x = 0.026 m.
m/s
(c) Repeat part (a) if friction acts on the block, with coefficient ?k = 0.160.
