## Homework Statement

Car A with mass 1000 kg is accelerating at 1ms

^{-2}at car B.

Car B with mass 1000 kg is accelerating at 1ms

^{-2}at car A.

What is the force on car B at the collision?

## Homework Equations

F = ma

Newton's third law

## The Attempt at a Solution

Car A force:

F = ma

F = 1000 x 1

F = 1000 N

Car B force:

F = ma

F = 1000 x 1

F = 1000 N

Then using Newton's third law, since every action has an equal opposite reaction force, if car B was colliding with a stationary object then the force on car B after colliding is 1000 N. But since car A is traveling at car B with 1000 N of force then that also has to be added into car B's total collision force. So therefore car B has a total collision force of 2000 N.

Is the answer right? Also is my explanation correct?
