Three astronauts, propelled by jet backpacks, push and guide a 120 kg asteroid towards a processing dock, exerting the force the force shown fing 5-29, with F1= 32 N, F2= 55N , F3= 41 N, θ1= 30 degree and θ3= 60 degree. What is the asteroid's acceleration (a) in unit vector notation and as (b) a magnitude and (c) a direction relative to the positive direction of the x axis?
