1. The problem statement, all variables and given/known data A 2.55 kg block is pushed 1.54 m up a vertical wall with constant speed by a constant force of magnitude F applied at an angle of 69.9 degrees with the horizontal. The acceleration of gravity is 9.8 m/s^2. If the coefficient of kinetic friction between the block and wall is 0.613, find work done by F. 2. Relevant equations W = F*x 3. The attempt at a solution t = theta u = coefficient of kinetic friction Fsint - uN = ma + mg ma = 0 (since it's constant speed) N = Fcost F = (mg + uFcost)/(sint) W = F * x I think my method is wrong because I end up with a F in the equation which I don't know. Please help me asap.
