PRACTICE IT
Use the worked example above to help you solve this problem. A block with mass of 5.79 kg is attached to
a horizontal spring with spring constant k = 3.32 x 10² N/m, as shown in the figure. The surface the block
rests upon is frictionless. The block is pulled out to x; 0.0510 m and released.
(a) Find the speed of the block at the equilibrium point.

(b) Find the speed when x = 0.029 m.
