Compute each part of given problem:
Problem: A car is traveling down a hill that makes an angle of 15° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μk = 0.52.
Part A: Find the acceleration of the car?
Part B: How long does the car take to skid to a stop if its initial speed is 30 mph (13 m/s)?
I want help to find How long does the car take to skid to a stop if its initial speed is 30 mph.
