Question

A man who is walking has a momentum of 80 kilogram meters per second west. The man has a mass of 80 kilograms. Which is the velocity of the man?

Answer 1

So, momentum is the product of mass times velocity. Some times, one just says mass times speed, but not in this problem. They ask for velocity, a vector.

vector momentum = mass * vector velocity,

So the velocity is 80/80 = 1 m/s west.
