Question

How much momentum does a 2500 kg mass moving at21. m/s have?kg*m/s (Round to 2 significant figures)

Answer 1

The momentum can be calculated with the following formula:

$p=mv$

Where m is the mass and v is the velocity.

So, for m = 2500 kg and v = 21 m/s, we have:

$\begin{gathered} p=2500\cdot21 \\ p=52500 \end{gathered}$

Rounding to 2 significant figures, we have a momentum of 53000 kg*m/s
