Answer:
5682 kg
Explanation:
The momentum of a moving object is given by:
[tex]p=mv[/tex]
where m is the mass of the object while v is its velocity.
In this problem, we know the velocity of the truck (v=22.0 m/s) and its momentum (p=125,000 kg m/s), therefore we can rearrange the previous formula to calculate the mass of the truck:
[tex]m=\frac{p}{v}=\frac{125,000 kg m/s}{22.0 m/s}=5682 kg[/tex]
