# I need help with a physics problem?

A 0.300-kg toy car moving with a speed of 0.860 m/s collides with a wall. The figure below shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

Update:
This course is algebra and trig based, therefore I do not know how to use calculus on this problem.
