Two ice skaters push off against one another starting from a stationary position. The 54.1-kg skater acquires a speed of 0.375 m/s. What speed does the 60.0-kg skater acquire

0.338125 m/s

Explanation:

Applying,

Law of conservation of momentum

m'v' = mv Equation 1

Where m' = mass of the first skater, v' = velocity of the first skater, m = mass of the second skater, v = velocity of the second skater.

make v the subject of the equation

v = m'v'/m Equation 2

From the question,

Given: m' = 54.1 kg, v' = 0.375 m/s, m = 60 kg

Substitute these values into equation

v = (54.1×0.375)/60

v = 20.2875/60

v = 0.338125 m/s
