Homework Statement
The braking distance is the distance the car travels while decelerating once the brakes have been applied. A car of mass 450kg is traveling at a speed of 70MPH (31.3ms-1) when the driver makes an emergency stop.
Calculate the deceleration of the car (Assume a uniform deceleration)
We're also told that at 70mph/31.3ms-1 that the breaking distance is 75 m.
The Attempt at a Solution
I did initially try to do this using the equations of motion but that gave me a huge answer, and didn't take into account the mass of the car so I didn't think it was right.
Any help is hugely appreciated!
