Question

Two skaters face one another and stand motionless, then push against each other on the ice. If one's mass is 55 kg and he moves to the left after the push at a velocity of 4.3 m/s, how fast was the other skater traveling after the push if her mass was 48 kg.​

Answer 1

3.75 m/s

Step-by-step explanation:

55/4.3 = 48/x

12.8 = 48/x

x = 48 : 12.8

x = 3.75 m/s
