Question

Part I: A solid sphere of mass M and radius R is released from rest on a ramp that makes an angle 0 with the horizontal. The sphere is initially distance d from the bottom of the ramp, and it rolls without slipping. Using the principle of energy conservation, find an expression for the speed v of the sphere when it reaches the bottom of the ramp. Your answer should be in terms of M, R, g, e, and d as needed*. h Part II: A projectile is launched with a speedv at an angle 0 below the horizontal at a height H above a level floor. It hits the floor after a horizontal displacement x Using your knowledge of projectile motion, find an expression that relates v,0, g, H, and x Н х, "as needed" means that these quantities can be in the final expression, but they will not necessarily be in it.
Please show all work. Thank you!
