A snow plough with a mass of m=8 metric tonnes (1 metric tonne=1,000kg) has an initial speed v1 16 m/s is clearing snow. The retarding force the snow produces on the snow plough satisfies the force-displacement relationship. Fsnow = 900+6000x2 where Fsnow is in Newtons and x is in metres. Each wheel have a radius of 0.5m and a mass moment of inertia of 3.75 kgm2. Assuming the wheels do not slip and friction can be ignored what is the speed of the snow plough after it travels a distance s=3m?
