Problem 22P

Two ice skaters stand at rest in the center of an ice rink. When they push off against one another the 45-kg skater acquires a speed of 0.62 m/s. If the speed of the other skater is 0.89 m/s, what is this skater's mass?

Solution 22P

Step 1 of 2:

Consider two ice skater initially at rest pushing them each other in an ice rink. The speed of the two persons and mass of one person are given. We need to find the mass of another person.

The mass of the person 1 m1 = 45 kg

The speed of the person 1 v1 = 0.62 m/s

The speed of the person 2 v2 = 0.89 m/s
