Question

A 20 Kg bike is moving at 6 m/s down a hill. What is the momentum of the bike?

Answer 1

Given data:

The mass of the bike is m = 20 kg.

The velocity of the bike is v = 6 m/s.

Solution:

The momentum of the bike in terms of mass and velocity is,

`p=mv`

Substituting the known values,

`\begin{gathered} p=20*6 \\ p=120\text{ kgm/s} \end{gathered}`

Thus, the momentum of the bike is 120 kgm/s.
