MOTION ON A HORIZONTAL ROUGH SURFACE
Laws of Motion

270329 Consider a 14-tyre truck, whose only rear 8 wheels are power driven (means only these 8 wheels can produce an acceleration). These 8 wheels are supporting approximately half of the load. If coefficient of friction between road and each tyre is 0.6 , then what could be the maximum attainable acceleration by this truck is
