Homework Statement
A lawn roller in the form of a thin-walled, hollow cylinder with mass M is pulled horizontally with a constant horizontal force F applied by a handle attached to the axle.
a)If it rolls without slipping, find the acceleration.
b)If it rolls without slipping, find the friction force.
Homework Equations
[itex]I_{Hollow Cylinder} = MR^{2}[/itex]
[itex]\sum \tau = f_{friction}R = I\alpha = MR^{2}\alpha[/itex]
[itex]\sum F = F - f_{friction} = F = Ma[/itex]
The Attempt at a Solution
I'm really not sure...it seems like I have too many unknowns (R, a, alpha, friction)
