0.4 m/s in the opposite direction of the ball's motion.

Explanation:

A 50 kg skater at rest on a friction less rink throws a 2 kg ball, giving the ball a velocity of 10 m/s. thus the subsequent motion of skater is 0.4 m/s in the opposite direction of the ball's motion. The calculation is follows as

2/50 = 0.4 m/s
