Steven carefully places a m = 1.45 kg wooden block on africtionless ramp so that the block begins to slide down theramp from rest. The ramp makes an angle of 0 = 53.3° upfrom the horizontal.Which forces do nonzero work on the block as it slidesdown the ramp?☐ gravityHow much total work Wnet has been done on the block after itslides down along the ramp a distance of 1.87 m?Nancy measures the speed of the wooden block after it hasgone the 1.87 m down the ramp. Predict what speed u sheshould measure.Now, Steven again places the wooden block back at the top ofthe ramp, but this time he jokingly gives the block a big pushbefore it slides down the ramp. If the block's initial speed is2.00 m/s and the block again slides down the ramp 1.87 m,what should Nancy measure for the speed v of the blockthis time?☐ springfrictionnormalJWnet=v =m/sv =m/s

FINAL ANSWER:- 1.gravity 2.Total work done 21.33J 3.speed of wooden block is 5.42m/s.…
