**1. Three astronauts, propelled by jet backpacks, push and guide a 148 kg asteroid toward a processing dock, exerting the forces shown in the figure, with F1 = 29 N, F2 = 54 N, F3 = 40 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. F=ma**

**3. So I've been trying to do this problem and I can't seem to figure it out. I'm on my last attempt on my online homework so I really need some help. Here's how far I've gotten:**

Ax=((29cos30)+(54cos0)+(40cos60))/148=0.667

Ay=((29sin30)+(54sin0)+(40sin60))/148=0.332

sqrt0.332

invertan(0.332/0.667)=26.5degrees

Ax=((29cos30)+(54cos0)+(40cos60))/148=0.667

Ay=((29sin30)+(54sin0)+(40sin60))/148=0.332
