Tension in a cable at an angle

  1. Sep 13, 2008 #1
    I'm having trouble finding what formula to use for this:

    A tow truck is connected to a 1400 kg car by a cable that makes a 25 degree angle to the horizontal.

    If the truck accelerates at 0.55 m/s^2, what is the magnitude of the cable tension? Neglect friction and the mass of the cable.

    Hi da5id2! Welcome to PF! :smile:

    The car obviously has the same acceleration as the truck, 0.55 m/s^2.

    So use good ol' Newton's second law for the external forces on the car in the horizontal direction. :wink:
