# A person riding a bike at 5m/s due west

A person is riding a bike at 5m/s due west. The mass of the rider + bike is 95 kg. The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the velocity is 5 m/s and the mass is 95 kg.

## Calculating Momentum

**Momentum = Mass x Velocity**

Momentum = 95 kg x 5 m/s

Momentum = 475 kg-m/s

So, the magnitude of the momentum of the rider + bike is 475 kg-m/s.

What’s is the magnitude of its momentum?5 m/s * 95 kg = 475 kg-m/s

Hope this helped :)
