Question

a 2403 kg racecar has a total momentum of 9.912*10^4kgm/s at one point in the race. calculate the speed of the racecar at that point

Answer 1

In order to calculate the speed, we can use the formula for the momentum:

`p=m\cdot v`

Where p is the momentum (in kg m/s), m is the mass (in kg) and v is the speed (in m/s).

So, using p = 99120 kg m/s and m = 2403 kg, we have:

`\begin{gathered} 99120=2403\cdot v\\ \\ v=(99120)/(2403)\\ \\ v=41.25\text{ m/s} \end{gathered}`
