Consider a plow pulled by two oxen. On the left side the ox pulls with a force of 500 N at an angle of 30 degrees from the vertical. On the right side, the other ox pulls with a force of 600 N at an angle of -45 degrees from the vertical. Determine the net force the plow experiences (magnitude and direction). If the plow has a mass of 100 kg, what is the magnitude of the acceleration it experiences?
