Constant Force

  1. Sep 18, 2007 #1
    A block of mass 8.3 kg is pulled along a horizontal frictionless floor by a cord that exerts a force of 53.0 N at an angle 25.3° above the horizontal. What is the magnitude of the acceleration of the block?

    I'm just wondering how I set up an equation with an angle.

    Separate the applied force into its horizontal and vertical components using the trigonometric ratios or use the method of tension co-efficients.

    That's where I'm having a problem.

    would it be something like:

    How about [tex]F_x = F(cos (\frac{\pi}{6})) [/tex] ?

    wow, how did you get that

    Yes, something like that. But of course the angle isn't 30 degrees.
