A ball is moving at 7.0 m/s and has a momentum of 100 kg-m/s. What is the ball's mass?

OpenStudy (anonymous):

well momentum = mass x velocity. you are given momentum and velocity: rearrange and solve for mass

OpenStudy (anonymous):

and the question you posted before this one is solved in a similar way. you just have mass instead of velocity

OpenStudy (anonymous):

14.28kg

OpenStudy (anonymous):

oky since the momentum is equal to mass into velocity. so by using momentum and velocity you can determine mass.
