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 construction worker pushes on a 10 kg crate down an inclined
plane that is 7.0 m long and is inclined at an angle of 20 degrees

the worker pushes directly on the crate in a direction parallel to
the incline with a force of 50 N for the entire length of the
plane. A)...

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. At what angle θ
above the horizontal surface should the force be applied to achieve
