The block shown has a mass of 51kg and is acted upon by a horizontal force P. The coefficient of friction is 0.40 between the body and the incline. Calculate the magnitude P required (a) barely to prevent the block from slipping down the incline, (b) to give the block an acceleration of 2.4 m/s2 up the incline.
