Two forces are acting on the 5 kg object, with only one of them shown in Fig. 1. Knowing that F = 20 N, 0 = 30 and that the object is moving at a constant acceleration of a = 12 m/s, find the second force: 1.1. As a magnitude and angle relative to the positive direction of the x axis 1.2. In unit-vector notation a 0 y F
