3. In the diagram below, a force P of 750 N is applied to the 350 kg block. Find the acceleration of the block and the reaction forces at contact points A and B if the coefficient of kinetic friction between the block and surface is 0.15. 700 mm 700 mm 300 mm 300 mm 400 mm 500 mm 500 mm 500 mm 500 mm RA = 1659 N Z 171 deg R= 2110 lb 2 171 deg a = 0.372 m/s to the right
