A car is travelling at 13ms-1 towards some traffic lights. When a driver sees the lights change to red, the car is at a distance of 25m from the stop line The reaction time of the driver is 0.7s and the condition of the road does not permit the car to decelerate greater than 4.5 ms-2. With brakes fully applied,how far from the stop line is tthe car when it stops? On which side of the line is the car?How to solve this physics kinematics question?Hyperphysics.info is very handy for any and all physics problems.
A quick hyper physics search for %26quot;motion%26quot; gives:

The first link has governing equations, diagrms, descriptions, and an online calculator!
Enjoy!
