Acceleration of the crate

  1. Sep 29, 2007 #1
    a 25.o kg crate that is initially at rest. note that the view is one looking down on the top of the crate. two forces F1 and F2 act over this crate and it begins to move. the coefficient of the kinetic frictional between the crate and the florr is u=.350. determine the magnitude and direction ( relative to the X axis) of the acceleration of the crate.

    use the formula; f=un
    then once you have f, subs it into f=ma
    rearrange it for acceleration. if the acceleration is a positive answer; it goes forward. if negative; backwards.
