Asked by Jimmy
A ball with a mass of 0.8 kg is kicked up the ramp with an initial speed of 22 m/s. What is the speed [m/s] of the ball at the top assuming no friction? Angle from which ball is kicked is 23 degrees and the horizontal leg is 7 feet long.

Hint: the elevation change of the ball is
H = 7 ft*0.3048 m/ft*tan 23 = 0.906 m
The PE gain is M g H
Subtract the PE gain from the initial KE to get the final KE. They use that for the speed at the top
