A worker develops a tension T in the cable as he attempts to move the 48-kg cart up the 21° incline. Determine the resulting acceleration a of the cart if (a) T = 135 N and (b) T = 222 N. Neglect all friction, except that at the worker's feet. The acceleration a is positive if up the slope, negative if down the slope. 48 kg 15 21
