The term 2 F comes from a force analysis in which we see that there are two segments of rope pulling equally on the block. We then solve this equation for F . Answer: F = (1/2) mg (sin θ + μk cos θ ) Hint and answer for Problem # 8

Webin short, friction plays a (kind of) role of a switch or a threshold. it turns on motion, if there's enough net external force applied. if not, it turns off and the system doesn't move. but once it starts to move, the friction could be smaller than when it began moving cause F_k <= F_s thus let the system move faster WebWith an incline that is frictionless and you have a block on it the block's weight is directed strait down but the normal force is perpendicular to the incline so when you add the force vectors you end up with a net force parallel to the incline pointing down and this is what causes the block to slide down the incline.
