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

5682 kg

Step-by-step 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=(p)/(v)=(125,000 kg m/s)/(22.0 m/s)=5682 kg`
