A semi is traveling down the highway at a velocity of v = 39.5 m/s. The driver observes a wreck ahead, locks his brakes, and begins to slide. The truck has mass m and a coefficient of kinetic friction between the tires and the road of μk = 0.25. Write an expression for the sum of the forces in the x-direction for the truck while braking. Using the results from that input an expression for the trucks acceleration, ax, while braking. What is the magnitude of the acceleration in m/s^2, and how far does the truck travel, d in meters, before stopping?
