well momentum = mass x velocity. you are given momentum and velocity: rearrange and solve for mass
and the question you posted before this one is solved in a similar way. you just have mass instead of velocity
14.28kg
@s2 don't just give answers, If you'll explain it'll help all.
oky since the momentum is equal to mass into velocity. so by using momentum and velocity you can determine mass.
