1. The problem statement, all variables and given/known data A 3.15 kg block is pushed along the ceiling with a constant applied force of F = 87.4 N that acts at an angle of alpha = 58.9° with the horizontal, as seen in the figure below. The block accelerates to the right at 5.49 m/s2. Determine the coefficient of kinetic friction between block and ceiling. 2. Relevant equations Ff=uN 3. The attempt at a solution Tried using the angle but dont know what to do. Any ideas?
