A bowling ball whose radius R is 0.11 m and whose mass M is 7.2 Kg, rolls from rest down a ramp whose length L is 21 m. The ramp is inclined at an angle θ of 34° to the horizontal ; ( Rotational inertia = ) a) How fast is the center of the ball moving when it reached the bottom of the ramp? Assuming the ball is uniform in density b) What is the kinetic energy associated with rotation and translation as the ball reached the bottom c) What is the angular velocity of the ball as it reached the bottom d) How much time does it take to reach the bottom
