The crane shown in the figure is lifting a 186-kg crate upward with an acceleration of 4.21 m/s². The cable from the crate passes over a solid cylindrical pulley at the top of the boom. The pulley has a mass of 195 kg. The cable is then wound onto a hollow cylindrical drum that is mounted on the deck of the crane. The mass of the drum is 136 kg, and its radius (the same as that of the pulley) is 0.198 m. The engine applies a counterclockwise torque to the drum in order to wind up the cable. What is the magnitude of this torque? Ignore the mass of the cable. Pulley- Drum Boom Number I Units N-m

RWS-1 Consider a bowling ball which is tossed down a bowling alley. For this problem, we will consider the bowling ball to be a uniform sphere of mass M and radius R, with a moment of inertia given by I= (2/5)MR2. The moment the ball hits the ground (t 0), it is moving horizontally with initial linear speed vo, but it is not rotating (oo = 0). Due to kinetic friction between the ground and the ball, it begins to rotate as it slides. The coefficient of kinetic friction is uk. As the ball slides along the lane, its angular speed steadily increases. At some point (time to), the "no-slip" condition kicks in, so that o = v/R. After this, the ball moves with a constant %3D %3D linear and angular speed. Solve all parts of this problem symbolically. a) Use Newton's second law to find an expression for the linear acceleration of the ball along the x-direction while the ball is slipping, ax. The free body diagram of the ball is shown below. Your final expression should only involve the variables…
