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 speed of the block at the bottom of the ramp is most nearly
A. 0
B. 5.5 m/s
C. 7.7 m/s
D. 9.5 m/s
E. 13 m/s
