How fast was the car initially going

Reference no: EM13326938

A car slams on its brakes and skids 50m before coming to a stop.

A) If the coefficient of kinetic friction is 0.65 how fast was the car initially going?

B) In newer cars antilock brakes prevent a car from skidding. Assume that an antilock brake system keeps the car and the road at the maximum amount of fricion at all times. If the static friction between the tires and the road is 0.89, how fast could the car be going to stop at exactly 50m?
