A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustrates. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 9.33 m/s at the bottom of the rise. Find the translational speed at the top. 0.760 m Number i Units

Constants A string is wrapped around a uniform solid cylinder of radius r = 0.6 m, as shown in (Figure 1). The cylinder can rotate freely about its axis. The loose end of the string is attached to a block. The block and cylinder each have mass m = 8.5kg Part A Find the magnitude a of the angular acceleration of the cylinder as the block descends.

Two blocks are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below. 1721 Mo i The masses of the blocks are m₁ = 16.0 kg and m₂ = 11.5 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.100 m. Block m₂ is initially on the floor, and block m₁ is initially 4.20 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the rope is small enough to be ignored, and the rope does not slip on the pulley, nor does it stretch. (a) How much time (in s) does it take block m, to hit the floor after being released? At₁ S (b) How would your answer to part (a) change if the mass of the pulley were neglected? (Enter the time, in seconds, it takes block m, to hit the floor if the mass of the pulley were neglected.) At₂

A baseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other movements.
