Two horses are pulling a barge with a mass 2000 kg along a canal. the cable connected to the first horse makes an angle of θ1= 40 o with respect to the direction of the canal, while the cable connected to the second horse makes an angle of θ2= -20o . find the acceleration of the barge (magnitude and direction), starting at rest, if each horse exerts a force of magnitude 600 n. ignore forces of resistance.
