Students set up an experiment with a small block on a ramp. The block of mass M=3.0 kg is released from rest at the top of the curved ramp. The length of the ramp as measured along the curve is L=3.0 m, and the height is h=1.5 m, as shown. There is negligible friction between the small block and the ramp. The students now move the block to a ramp that is identical to the first one except that it has a rough surface. Figure 1 shows the block as it is sliding down the ramp. Figure 2 shows a free-body diagram for the block when it is at the moment shown in Figure 1. Which of the following claims is supported by the figures?
