Question

A 36,287 kg truck has a momentum of 907,175 kg • . What is the truck’s velocity?

Answer 1

The momentum of an object is equal to its velocity multiplied by its mass: P = mv Rearranging the equation, the truck's velocity is equal to its momentum divided by its mass: v = P/m = 907175 / 36,287kg = 25.

Answer 2

Given:
m = 36,287 kg, the mass of the truck
P = 907,175 (kg-m)/s, the truck's momentum.

Let v = the truck's velocity.
By definition, the momentum is
P = m*v
Therefore
v = P/m
= (907175 (kg-m)/s) / (36287 kg)
= 25 m/s

Answer: 25 m/s
