A 0.59-kg object connected to a light spring with a force constant of 24.0 N/m oscillates on a frictionless horizontal surface. The spring is compressed 4.0 cm and released from rest.
(a) Determine the maximum speed of the object. m/s
(b) Determine the speed of the object when the spring is compressed 1.5 cm. m/s
(c) Determine the speed of the object as it passes the point 1.5 cm from the equilibrium position. m/s
(d) For what value of x does the speed equal one-half the maximum speed?
