Our friend Bob is trying to pull a very heavy crate by pulling an attached rope at an angle of 0=0.333 degrees above
the horizontal.
There exists coefficients of friction u=0.645, and µy={muk} between the crate and the box.
The mass of the crate is 386.
Using g = 9.81 m/s?, what is the minimum required for that Bob must pull with in order for the box to begin moving?
Once you have finished this problem, please also determine with what acceleration the box will be moving
immediately after the box begins to slide. You do not need to submit this second portion of the problem.
