Question

A 60kg girl standing on rollerskates (with no friction between the skates and the ground) throws a 5kg medicine ball to the right with a speed of 6m/s. Find the recoil velocity of the skater.

Answer 1

The recoil velocity of the skater is V1= 0.5 m/s

Step-by-step explanation:

m1= 60 kg

V1= ?

m2= 5kg

V2= 6 m/s

m1*V1 = m2*V2

V1= (m2*V2) / m1

V1= 0.5 m/s
