Question

Using the momentum formula, calculate the momentum of a 325 kg rock, rolling down a hill at 1.75 m/s.

Answer 1

We will have the following:

First, we recall that momentum is given by:

`\tau=m\ast v`

So:

`\tau=(325kg)(1.75m/s)\Rightarrow\tau=568.75kg\ast m/s`

So, the momentum of the rock is 568.75 kg*m/s.
