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 truck drags a 200 kg log, initially at rest, across the (flat) ground for 10 meters, and then up a 30-degree incline. If the truck pulls with a constant force of 20,000 Newtons, and the coefficient of friction between the wood and ground is 0.2 for the entire duration of the journey, once log has traveled 10 meters along the incline, what is the log’s speed in m/s? Hint: use conservation of energy to solve this problem, using the...
