Three astronauts, propelled by jet backpacks, push and guide a 129 kg asteroid toward a processing dock, exerting the forces shown in the figure, with F1 = 35.0 N, F2 = 59.0 N, F3 = 44.0 N, 01 = 30.09, and 03 = 60.0. What is the (a) magnitude and (b) angle (measured relative to the positive direction of the x-axis in the range of (-180, 180]) of the asteroid's acceleration? Fi X F2
