A box of mass 730 kg is being pulled at a constant speed across a rough horizontal floor by a constant force, F. The angle of this force above the horizontal is such that the force you apply is a minimum (that is, the amount of force you need to move the box at a constant speed across the floor depends on the angle at which you pull - find the angle which the force is a minimum). Calculate the...

A 6.53-kg block initially at rest is pulled to the right along a horizontal surface by a constant force of 125 N applied at an angle θ above the horizontal. The coefficient of kinetic friction between the block and the horizontal surface is 0.150.
