The driver of an empty speeding truck slams on the brakes and skids to a stop in a distance Dm = 254.84 m. The truck's initial velocity is v0 = 50 m/s and its total mass is m = 3137.8 kg. The coefficient of kinetic friction between the tires and the road is mk = 0.5

If the truck were carrying an amount of cargo that doubled its total mass, what would its stopping distance have been? (Assume the road is straight and horizontal).

D2m = m
