Question

What is the increase in momentum if a net force of 253 N is applied to a box for 27.3 s?

Answer 1

In order to calculate the increase in momentum, we can use the following impulse theorem:

`\Delta p=F\cdot\Delta t`

Where Delta p is the change in momentum, F is the force and Delta t is the time interval.

So, using F = 253 N and Delta t = 27.3 s, we have:

`\begin{gathered} \Delta p=253\cdot27.3 \\ \Delta p=6906.9\text{ kg m/s} \end{gathered}`

Therefore the increase in momentum is 6906.9 kg m/s.
