1. The problem statement, all variables and given/known data Three movers are applying forces F1 = 100 N [W20°N], F2 = 200 N [E40°S], and F3 = 300 N on a 300-kg grand piano. If μK for the piano is 0.10, determine a) the net force acting on the piano b) the acceleration of the piano 3. The attempt at a solution I got an answer of 395 N going down and 276.9 going left. Fnet = 482.38N But the answer sheet says 106N :( Help please.
