[SOLVED] Magnitude and acceleration 1. The problem statement, all variables and given/known data Three astronauts, propelled by jet backpacks, push and guide a 130 kg asteroid toward a processing dock, exerting the forces shown in the figure, with F1 = 32 N, F2 = 52 N, F3 = 39 N, θ1 = 30°, and θ3 = 60°. What is the (a) magnitude and (b) angle (measured relative to the positive direction of the x axis) of the asteroid's acceleration? 2. Relevant equations F=ma 3. The attempt at a solution If i had to make a guess....would i add the forces up which would be...129=ma where m is 130kg? Or would the magnitude be each mass squared and the square root of those sums which would be 72.45 in this case?
