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:
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) ?![Big Grin :biggrin: :biggrin:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
