Question

when a particular football player is running at 2.5m/s, he has 227kgm/s of momentum. calculate the mass of the football player.

Answer 1

In order to calculate the mass of the player, 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 = 227 and v = 2.5, we have:

$\begin{gathered} 227=m\cdot2.5\\ \\ m=\frac{227}{2.5}\\ \\ m=90.8\text{ kg} \end{gathered}$
