With what velocity Must a 0.53 kg softball be moving to be equal to the momentum of a 0.31 kg baseball moving at 21 m/s

Answer:12.28m/s

Explanation:

momentum of baseball = mass of baseball x velocity of baseball

Momentum of baseball = 0.31x21

Momentum of baseball = 6.51kgm/s

For a softball to have same momentum with the baseball we can say : momentum of baseball = mass of softball x velocity of softball

6.51=0.53 x velocity of softball

Velocity of softball = 6.51/0.53

Velocity of softball = 12.28m/s
