(adsbygoogle = window.adsbygoogle || []).push({}); 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.
