A 0.500-kg object is connected to a horizontal massless spring. The spring is initially stretched by 0.200 m and the object is released from rest there. It proceeds to move without friction. The next time the speed of the object is zero is 0.500 s later. Determine the maximum speed of the object, the spring constant, and the mechanical energy of the system. Determine potential energy of the object when it’s speed is a third of the maximum speed.
