(Q) Find the maximum speed at which a truck can safely travel without toppling over, on a curve of radius 250m. The height of the centre of gravity of the truck above the ground is 1.5m and the distance between the wheels is 1.5m, the truck being horizontal.
I actually can't figure out which force acts as the centripetal force in the question. Also since it is a truck so it can't lean, so I can't apply the method we generally use in leaning of cycle. Also no friction is described here between the road and wheels.
