Homework Help: Student Pulling Box

  1. Apr 16, 2008 #1
    1. The problem statement, all variables and given/known data

    The student in item 1 (in parenthesis below) moves the box up a ramp inclined at 12 degrees with the horizontal. If the box starts from rest at the bottom of the ramp and is pulled at an angle of 25 degrees with respect to the incline and with the same 185N force, what is the acceleration up the ramp. Assume the mu is 0.27.

    (A student pulls on a rope attached to a box of books and moves the box down the hall. The student pulls with a force of 185N at an angle of 25 degrees above horizontal. The box has a mass of 35 kg and mu between the box and the floor is 0.27. Find the acceleration.)

    2. Relevant equations

    3. The attempt at a solution
    Would the answer be 2.9 m/s^2?
