# Finding intial momentum

**1. The problem statement, all variables and given/known data**

You are riding in a car that crashes into a solid wall. The car comes to a complete stop without bouncing back. The car has a mass of 1500 kg and has a speed of 30 m/s before the crash.

What is the car’s initial momentum? What is your initial momentum? (Recall that the weight

of one kilogram is 2.2 lbs) What is the change in the momentum of the car? What is the

change in your momentum?

**2. Relevant equations**

**3. The attempt at a solution**

CarI= (1500kg) X (30m/s)= 45000kg m/s

YouI=(Mass) X (30 m/s)

Car change= (1500kg) X (-30m/s)= -45000kg m/s

You change= (Mass) X (-30m/s)
