Homework Statement
A gardener pushes down on the handle of a lawnmover, applying a force of 250N. The handle is inclined at an angle 45* to the horizontal. If the coefficient of the kinetic friction between the wheels of the lawnmower and the ground is 0.40, what is the acceleration of the 20-kg lawnmower?
Homework Equations
Fnet=0=Fn+Fsin45-Fg
Fn=mg-FSin45
a=(Fx-Ff)/m
Fnet=ma
Ff=(UkFn) Uk=coefficient of friction miew? or meiu
The Attempt at a Solution
Answer is 1.38m/s^2
