Question

Suppose a truck has a momentum of 40,120 kg • and a mass of 1,180 kg. what is the truck’s velocity?

Answer 1

The momentum of an object is the product between the mass m of the object and its velocity:
$p=mv$
The truck in our problem has momentum equal to
$p=40120 kg m/s$ 
and a mass of
$m=1180 kg$
so, if we re-arrange the previous formula, we can use these data to find the velocity of the truck:
$v= \frac{p}{m}= \frac{40120 kg m/s}{1180 kg}=34 m/s$

Answer 2

34m/s is the correct answer!
