At the airport, you pull a 20 kg suitcase across the floor with a strap that is at an angle of 50 ∘ above the horizontal.

A) Find the normal force, given that the suitcase moves with constant speed and that the coefficient of kinetic friction between the suitcase and the floor is 0.34.

B) Find the tension (in Newtons) in the strap, given that the suitcase moves with constant speed and that the coefficient of kinetic friction between the suitcase and the floor is 0.34.

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...
