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...

question 1: Let A be the last digit, let B be the second to last digit, and let C be the sum of the last three digits of your 8-digit student ID. Example: for 20245347, A = 7, B = 4, and C = 14. Starting from rest, a student pulls a (25.0+A) kg box a distance of (4.50 + B) m across the floor using a (134 + C) N force applied at 35.0 degrees above horizontal. The coefficient...
