Answer:
6m/s
Explanation:
Data obtained from the question include:
Mass = 0.5kg
Momentum = 3 kg.m/s
Velocity =.?
Momentum is simply the product of mass and velocity as shown by the equation below:
Momentum = Mass x Velocity
Velocity = Momentum /mass
Velocity = 3kg.m/s / 0.5kg
Velocity = 6m/s
Therefore, the velocity of the ball is 6m/s
