-1.07 1.07 2 3 4 5 Time (s) A cart of mass 2.0 kg on a horizontal surface is attached to a horizontal spring of negligible mass. A 1.0 kg block is secured on top of the of the 2.0 kg cart The other end of the spring is attached to a wall, and there is negligible friction between the cart-block-spring system and the horizontal surface The cart-block-spring system then experiences simple harmonic motion as described by the graph that shows the velocity of the cart block system as a function of time. The maximum spring potential energy of the cart-block-spring system is most nearly A. 0.32 J
B. 0.64 J
C. 0.96 J
D.1.92 J​
