A car of mass 1.2 tonnes is travelling along a straight horizontal road at a speed of 20 ms' when it brakes sharply then skids. Friction brings the car to rest. If the coefficient of friction between the tyres and road is
0.8, calculate the distance travelled by the car before it comes to rest.​

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
