Suppose a 0.250-kg ball is thrown at 12.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in the figure below. (a) Vi (a) Calculate the final linear velocity of the person, given his mass is 80.0 kg. m/s Enter a number. (b) (b) What is his angular velocity if each arm is 5.00 kg in mass? You may treat his arms as uniform rods of length 0.9 m (measured from the center axis of his body) and the rest of his body as a uniform cylinder of radius 0.170 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. rad/s (c) Compare the initial and final total kinetic energy. KE KE
