Homework Help: Find Acceleration with an angle

  1. Nov 17, 2008 #1
    1. A clerk moves a box of cans down an aisle by pulling on a strap attached to the box. The clerk pulls with a force of 185.0 N at an angle of 25.0 degrees with the floor. The box has a mass of 35.0 kg, and the coefficient of kinetic friction is 0.450. Find the Acceleration of the box.

    2. Relevant equations
    Find the accerlation.

    3. I have no idea how to do this. please help!

    Welcome to PF.

    Draw a force diagram. The normal force of the weight looks like it will be offset by the vertical up component of the force.

    So that leaves the net normal force down times the coefficient of friction opposing the horizontal component of the force. That net force divided by the mass gives you the acceleration.
