Question

3. An truck with a mass of 3500 kg travels with a velocity of 22.0 m/s. Find the momentum. (2 sigfigs) (in

Answer 1

The linear momentum (p) of an object with mass m and speed v is given by:

$p=mv$

Replace m=3500kg and v=22.0m/s to find the linear momentum of the truck:

$\begin{gathered} p=(3500\operatorname{kg})(22.0\frac{m}{s}) \\ =77,000\operatorname{kg}\frac{m}{s} \end{gathered}$

Therefore, the linear momentum of the truck is 77,000 kg*m/s.
