Multiple Choice

For this question,assume that all velocities are horizontal and that there is no friction.Two skaters A and B are on an ice surface.A and B have the same mass M = 90.5 kg.A throws a ball with mass m = 200 g toward B with a speed v = 21.5 m/s relative to the ice.B catches the ball and throws it back to A with the same speed.After A catches the ball,his speed with respect to the ice is

A) 4.3 $\times$ 10³ m/s
B) 4.3 m/s
C) 4.8 $\times$ 10^-2 m/s
D) 9.5 $\times$ 10^-2 m/s
