Suppose a 0.250-kg ball is thrown at 15.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in Figure 10.40.
(a) Calculate the final linear velocity of the person, given his mass is 70.0 kg.
(b) What is his
(c) Compare the initial and final total kinetic energies.
Figure 10.40 The figure shows the overhead view of a person standing motionless on ice about to catch a ball. Both arms are outstretched. After catching the ball, the skater recoils and rotates.
