A solid, uniform ball rolls without slipping up a hill. At the top of the hill, it is moving horizontally; then it goes over the vertical cliff. Take V = 25.0 m/s and H = 30.0 m . Part A: How far from the foot of the cliff does the ball land? Part B: How fast is it moving just before it lands? Part C: Notice that when the ball lands, it has a larger translational speed than it had...

A person kicks a ball, giving it an initial velocity of 20.0 m/s up a wooden ramp. When the ball reaches the top, it becomes airborne. The ramp makes an angle of 22.0º to the ground, and the ball travels a distance of 5.00 m on the ramp. What is the maximum height the ball reaches, above the point where it was kicked, if (a) the ramp is frictionless and (b) there is a coefficient of friction of 0.150 between...
