Homework Statement
Consider a lawnmower of weight "w" which can slide across a horizontal surface with a coefficient of friction "u". In this problem the lawnmower is pushed using a massless handle, which makes an angle "0" with the horizontal. Assume that F(h), the force exerted by the handle, is parallel to the handle.
Take the positive x direction to be to the right and the postive y direction to be upward.
Homework Equations
n-w-F(h)*sin(0) = 0 = Fx
-F(h)cos(0)+F(f)= 0 = Fy
0 = pheta
solving for F(h)
n - normal force
w - weight
F(f) friction
The Attempt at a Solution
(n-w-F(f))/(-sin(0)+cos(0))
the correct answer does not involve F(f) and n.
HELP!
