Margie’s 15 kg brother Luke sits on a sled. Margie pulls the sled across the floor using a rope that is angled 20° above the floor. The tension is a constant 30 N and the coefficient of friction is 0.20. Use work and energy to find Luke’s speed after being pulled 3.0 m.
A box of mass 730 kg is being pulled at a constant speed across a rough...
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 box with mass 1.74 kg is being pulled across a rough surface at a constant speed with a coefficient of kinetic friction µk = 0.366. The pulling force has a magnitude of 11.2 N and is directed at an angle 32.8 degrees above horizontal. If the box is dragged a distance of 10.3 m, what is the total energy lost to friction? (Hint: be sure to account for the upward component of the pulling force, and note that the...
