A spherical bowling ball with mass m = 4.6 kg and radius R = 0.105 m is thrown down the lane with an initial speed of v = 9.5 m/s. The coefficient of static friction between the ball and the ground is 0.35 and the coefficient for kinetic friction is μ = 0.3. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down the lane? 2) What is magnitude of the linear acceleration of the bowling ball as it slides down the lane? 3) How long does it take the bowling ball to begin rolling without slipping? 4) Once it begins to roll without slipping, what is the force of friction on the ball?

The three masses in the figure are different. The planes do not have friction with the masses and the plane of mass 3 corresponds to a quarter of a circumference. All three masses are released at the same time. The masses m2 and m3 travel the same distance. The first mass that will reach the bottom of the ramp will be: m1 m2 m3 m2 and m3 m1 and m2 m1 and m3 they will all arrive at the same time
