Physics , please help me Lamia noticed while she was riding a bicycle, a broken tree blocking the road at a distance of 42 meters. If the coefficient of kinetic friction between the tires of her bike and the road was 0.36, while she was driving her bike at a speed of 25.0 km h, what distance would be required to stop, knowing that the mass of Lamia and the bike together is 95 kg
