The ball B has a mass of 14 kg and is attached to the end of a rod whose mass may be neglected as shown in (Figure 1). Part A: If the rod is subjected to a torque M=(3t2+5t+2) N⋅m where tt is in seconds, determine the speed of the ball when t = 2 s. The ball has a speed v= 2 m/sm/s when t = 0. Express your answer to three significant figures and include the appropriate units.
