Question

A 2200 kg car is travelling at 45 km per hour when its brakes are applied and it skids to a stop. If the coefficient of friction between the road and the tires is 0.70 how far does the car go before stopping?

Answer 1

Vf^2=Vi^2+2ad where a= -F/mass=-mu*mg/m=-mu*g

solve for d.

Answer 2

11.3m i think
