Question

A block of mass 10 kg is placed at a distance of 5 m from the rear end of a long trolleyes shown in figure. The coefficient of friction between the block and the surface below is 0.2. Starting from the rest, the trolley is given a uniform acceleration of 3 ms. At what distance from the starting point will block fall off the trolley! Take $g = 10 m s^{- 3}$
