hey everybody, i have an easy problem in friction, i just want to make sure if what i did is right; here is the problem:(adsbygoogle = window.adsbygoogle || []).push({});

A 22kg mass is slid up an incline of 71degree to the horizontal at constant velocity. If mu=.29, what is the applied force?

here is what i did:

Fgravity = 22*9.8*cos(71) = 70.19

Fparallel = 22.9.8*sin(71) = 203.85

Ffriction = 70.19/.26 = 269.96

Fapplied = 269.96+203.85 = 473.81 N

do u think that is right (not the calculations, but the formulas i used) ?
