momentum (p) is 88 kg * m/s, velocity (v) is 2 m/s. find mass (kg)
Mass*velocity=momentum
solve for mass.
I noted your use of the symbol p for momentum. This symbol is in use with Huygens latin word 'percussion', which Huygens used to describe the 'force' with which a cannon ball was discharged from a cannon. We call that momentum now, but his use of the word led to the symbol p. Someday, that trivia will be useful to you on some extracredit trivia question.
Good luck.
