A 15-kg block is on a ramp which is inclined at 20° above the horizontal. It is connected by a string to a 19-kg mass which hangs over the top edge of the ramp. Assuming that frictional forces may be neglected, what is the downward acceleration of the 19-kg block? 4.0 m/s2, 4.5m/s2, 4.2 m/s2, 3.8m/s2
