Three astronauts, propelled by jetpacks, push a 120kg asteroid toward a processing dock, exerting the forces(adsbygoogle = window.adsbygoogle || []).push({});

F1 = 32N at 30 degrees above the horizontal

F2 = 55N on the horizontal

F3 = 41N below 60 degrees below the horizontal

what is the asteroids acceleration in unit vector notation?

m = 120kg

F2 = (5N)i

F1+F2+F3 = ma

F1 = (32N cos30deg) , (32N sin30deg)

F1 = (27.7)i + 16j

F3 = (41N cos-60deg) , (41N sin-60deg)

F3 = (20.5N)i - (35.5N)j

Fnet = ma

Fnet/m = a

(27.7/120 +55 + 20.5/120)i , (-35.5/120 + 16/120)j = a

Is this right so far?
