A mass M = 21.00 kg is suspended by a massless string from the ceiling of a van which is moving with constant acceleration a, as shown in the figure. If the string makes an angle theta = 28.00 degrees with respect to the vertical, what is the acceleration a of the van?

  1. horizontal acceleration= van
    vertical acceleraton= g

    tan28=horizontal/g

    solve for horizontal acceleration
