Two horses are pulling a barge with a mass of 2.00 x 103 kg along a canal. The cable connected to the first horse makes an angle of 30.0° with respect to the direction of the canal, while the cable connected to the second horse makes an angle of 45.0°. Find the initial acceleration of the barge, starting at rest, if each hour exerts a force of magnitude 6.00 x 102 N on the barge. Ignore forces of resistance on the barge.
