A block of mass 15kg is placed on a long trolley. The cofficient of fricition between the block and trolley is 0.18. The trolley accelerates from rest with `0.5m//s^(2)` for 20s. then what is the friction force:-

A block of mass 15 kg is placed on a long trolley . The coefficient of friction between the block and the trolley is 0.18 . The trolley accelerates from rest with 0.5ms^(-2) for 20s and then moves with uniform velocity. Discuss the motion of the block as viewed by (a) a stationary observer on the ground (b) as observer moving with the trolley.
