Let m = mass of the block From the freebody diagram‚ R – mg = 0 R = mg ...(1) Again ma – R = 0 ma = R = mg (from (1)) a = g 4 = g = 4/g = 4/10 = 0.4 The co-efficient of kinetic friction between the block and the plane is 0.4 2. Due to friction the body will decelerate Let the deceleration be ‘a’ R – mg = 0 R = mg ...(1) ma – R = 0 ma = R = mg (from (1)) a = g = 0.1 × 10 = 1m/s2. Initial velocity u = 10 m/s Final
