A bale of hay of mass 15.0 kilogram is pulled at a constant velocity across a barn floor by a hook that pulls at an angle of 30o with the horizontal with a force of 30.0 Newton.
(a) Draw a complete well-labeled diagram for the hay bale?
(b) Find the normal force of the floor on the hay bale?
(c) Find the coefficient of kinetic friction between the hay bale and the barn floor?
