A car being driven at a constant speed past a speed camera.The camera recorded two images of the car 0.70 s apart.The car travelled 14 m between the two images being taken.The maximum deceleration of the car is 6.25 m/s2 Calculate the minimum braking distance for the car at the speed it passed the speed camera.

What have you tried?

Afaict the question needs you to...
1. calculate the constant speed of a car that covers 14m in 0.7 seconds
2. calculate the distance it would take to decelerate to stationary from that speed at a rate of 6.25 ms^-2 if the driver were to apply the brakes at maximum.
