The 64.4-lb crate slides down the curved path in the vertical plane. if the crate has a velocity of 3 ft/sec down the incline at a and a velocity of 25 ft/sec at b, compute the work uf. done on the crate by friction during the motion from a to b.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

the right answer is 0.3 meters per second

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
