Question

A large truck is moving at 22.0 m/s. If its momentum is 125,000 kg • , what is the truck's mass?

Answer 1

The mass of the truck is 5680 kg

Answer 2

Answer:

5682 kg

Explanation:

The momentum of a moving object is given by:

$p=mv$

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:

$m=\frac{p}{v}=\frac{125,000 kg m/s}{22.0 m/s}=5682 kg$
