A mountain bike with a mass 18kg, with a rider having mass 70 kg, is travelling at 20 km/h when the rider applies the brakes, locking the wheels. How far does the bike travel before coming to a stop the coefficient of friction between the rubber tires and the asphalt road is 0.65?How far does the bike travel before coming to a stop?20 km/h = 5.556 m/s



螖E = 0



陆 mv虏 - 渭 m g S = 0



cancled out of variabel "m"



陆 (5.556)虏 - (0.65)(9.8) S = 0



S = 2.42301 m
