At time t = 0, the operator of the road roller disengages the transmission so that the vehicle rolls down the incline (see Figure). Determine an expression for the vehicle's speed as a function of time. The two rear wheels weigh 500 lb each and have a radius of 4 ft. The front wheel weighs 800 lb and has a radius of 2 ft. The vehicle body weighs 9000 lb. Assume the wheels roll without slipping.
