Homework Statement
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.
Homework Equations
W = F*x
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.
