[QUOTE="kaspis245, post: 5002575, member: 534046"] [h2]Homework Statement [/h2] A 225 kg crate rests on a surface that is inclined above the horizontal at an angle of 20[SUP]o[/SUP]. A horizontal force (F = 535 N parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of friction between the crate and the incline? [B]P.S. F[SUB]tr[/SUB] is a frictional force.[/B] [ATTACH=full]175989[/ATTACH] [h2]Homework Equations[/h2] Newton's laws of motion. [h2]The Attempt at a Solution[/h2] [ATTACH=full]175990[/ATTACH] [ATTACH=full]175991[/ATTACH] It doesn't work. The answer must be 0.665 .[/B] [/QUOTE]
