You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...

By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...

A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of magnitude F = 460 N on the rope, which is inclined at angle θ = 35° to the horizontal, and the floor exerts a horizontal force of magnitude f = 100 N that opposes the motion. Calculate the magnitude of the acceleration of the crate if (a) its mass is 360 kg and (b) its weight...
