Question

A seasoned mini golfer is trying to make par on a tricky hole *5. The golfer can complete the hole by hitting the ball from the flat section it lays on, op a 45 degree ramp launching the ball into the hole which is d = 1.00 m away from the erxJ of the ramp. If the opening of the hole and the end of the ramp are at the same height, y = 0.680 m. at what speed most the gofer nrt the ball to land the ball in the hole? Assume a frictionless surface and the acceleration due to gravity is 9.81 m/s2.

Explanation / Answer

for the ball to land on hole it must have a minimal velocity at the entrance of hole. so from energy balance, mgh+0.5mvf^2=0.5mvi^2 =>2gh=vi^2 [vf=0] =>vi=(2gh)^0.5=(2x9.8x0.68)^0.5=3.651 m/s
