Suppose a 0.230 kg ball is thrown at 18.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in the figure below. (a) Calculate the final linear velocity (in m/s) of the person, given his mass is 92.0 kg. m/s (b) what is his angular velocity (in rad/s) if each arm is 8.00 kg? You may treat the ball as a point mass and treat the person's arms as uniform rods (each has a length of 0.810 m) and the rest of his body as a uniform cylinder of radius 0.170 m. Neglect the effect of the ball on his center of mass so that his center of mass remains in his geometrical center. rad/s (c) Compare the initial and final total kinetic energies. O Initial kinetic energy is the same as final kinetic energy. O Initial kinetic energy is less than final kinetic energy. O Initial kinetic energy is greater than final kinetic energy.
