Steven carefully places a m = 1.45 kg wooden block on a frictionless ramp so that the block begins to slide down the ramp from rest. The ramp makes an angle of 0 = 53.3° up from the horizontal. Which forces do nonzero work on the block as it slides down the ramp? ☐ gravity How much total work Wnet has been done on the block after it slides down along the ramp a distance of 1.87 m? Nancy measures the speed of the wooden block after it has gone the 1.87 m down the ramp. Predict what speed u she should measure. Now, Steven again places the wooden block back at the top of the ramp, but this time he jokingly gives the block a big push before it slides down the ramp. If the block's initial speed is 2.00 m/s and the block again slides down the ramp 1.87 m, what should Nancy measure for the speed v of the block this time? ☐ spring friction normal J Wnet = v = m/s v = m/s
