(6%) Problem 8: A bowling ball rolls without slipping at a speed of v_(i). It encounters a ramp of
vertical height h. Treat the ball as a uniform, solid sphere.
25% Part (a) Write an expression for the speed of the ball when it reaches the top of the ramp. Your answer will be in terms of g,h and v_(i).
v_(f)=sqrt()(v_(i)^(2)(-5gh)/(3))|

25% Part (b) If the ball's initial speed is 4.74(m)/(s), and the height of the ramp is 0.33m, what is the ball's speed, in meters per second, when it reaches the top
of the ramp? (Assume g=9.81(m)/(s^(2)).)
A 25% Part (c) Write an expression for h_(max), the maximum value of h, where the ball just reaches the top of the ramp. Your answer will be in terms of g and v_(i).
Delta 25% Part (d) What is the maximum height, in units of meters, where the ball just reaches the top of the ramp?
