Three astronauts, propelled by jet backpacks, push and guide a 120 kg asteroid toward a processing dock, exerting the forces with F1=32 N, with an angle of 30 degrees from the x-axis, F2=55 N along the x-axis, and F3=41 N with an angle of -60 degrees from the x-axis. WHat is the asteroid's acceleration, in vector notation and as a magnitude, and a direction relative to the positive direction of the x axis?

F=ma or force=mass times acceleration. You know the mass and forces involved. Solve all in the x direction and sum. Solve all in the y direction and sum. You then have two parts of a right triangle. You can just use trig. to get the angles. Remember to observe the signs or positive and negative notions of travel. You might have to subtract during the summation process.
