A 0.53-kg object connected to a light spring with a force constant of 23.8 N/m oscillates on a frictionless horizontal surface. The spring is compressed 4.0 cm and released from rest, after which it begins to oscillate.
(a) Determine the maximum speed of the object.
cm/s
(b) Determine the speed of the object when the spring is compressed 1.5 cm.
cm/s
(c) Determine the speed of the object when the spring is stretched 1.5 cm.
cm/s
(d) For what value of x does the speed equal one-half the maximum speed?
cm
