A 0.50-kg cart on an air track receives a push as shown in the animation (position in meters and time in seconds). The spring is initially unstretched with a spring constant of k=100N/m.
Determine the magnitude of the force required to hold the block in place and the work done by the external agent. Start
75 N / 28 J.
