Suppose a 0.250 kg ball is thrown at 13.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in Figure 9.31.
(a) Calculate the final linear velocity of the person, given his mass is 80.0 kg.
(b) What is his angular velocity if each arm has a 5.00 kg mass? You may treat his arms as uniform rods of length 0.9 m and the rest of his body as a uniform cylinder of radius 0.190 m. Neglect the effect of the ball on his rotational inertia and on his center of mass, so that it remains in his geometrical center.
(c) Compare the initial and final total kinetic energy.

A student sitting on a frictionless rotating stool has rotational inertia 0.96 kg⋅m2 about a vertical axis through her center of mass when her arms are tight to her chest. The stool rotates at 7.35 rad/s and has negligible mass. The student extends her arms until her hands, each holding a 5.0 kg mass, are 0.80 m from the rotation axis. Ignoring her arm mass, what's her new rotational velocity? Repeat if each arm is modeled as a 0.80 m...

As part of a carnival game, a 0.528-kg ball is thrown at a stack of 18.8-cm tall, 0.383-kg objects and hits with a perfectly horizontal velocity of 12.8 m/s. Suppose the ball strikes the topmost object as shown to the right. Immediately after the collision, the ball has a horizontal velocity of 3.60 m/s in the same direction, the topmost object now has an angular velocity of 1.63 rad/s about its center of mass and all the objects below are...
