Question

Your car is stopped at a red light. When the light turns green you accelerate at a constant rate of a0 for 4.4 seconds. Then, as you notice the next light turning red, you slam on your brakes, slowing at a rate of -17 m/s2 and bringing your car to rest exactly at the light as it turns red. Inspecting the tire marks that you left on the road, you determine your stopping distance to be 18.1 meters.

Determine your initial acceleration: a0
