1. The problem statement, all variables and given/known data a crate with mass m rests on a horizontal floor. a woman pushes down at an angle of theta below the horizontalon the frace with a force F, the coefficient of kinetic friction is Uk. a) what magnitude of force F is required to keep the crate moving at a constant velocity? 2. Relevant equations Ff(frictional force)=UkFn Constant velocity which means Fnet=0 3. The attempt at a solution since Fnet is 0 you can set horizontal force = to frictional force Ff=Fsin(theta) Uk(mg + Fcos(theta))=Fsin(theta) (Uk(mg+ Fcos(theta))/sin theta = F This is apparently not right and i cant thing of what else to do -_- help would be very much appreciated as well as an easier way of approaching problems with only symbols. thanks!
