A truck has a velocity of 25 m/s and a momentum of 25.000 kg*m/s. What is its
mass?

1000kg

Explanation:

We can use the equation "p=mv"

If we rearrange the equation to find mass (m), then the equation becomes:

m=p/v

We can substitute in the values of p and v as they are already given in the question.

So, now we just substitute in the values to get our answer.

m=p/v

m=25,000/25

m=1000kg
