Ok, got it! Thank you!

Ok, I think I’ve got it. I used μs=Fs/N, but I think Fs=Fnet so I replaced Fs with ma and N with mg. Then m cancels out and I end up with μs=a/g.

Thanks for replying! Above is my free body diagram. It’s not sliding, but I put the force Fx opposite to the static friction because I thought the forces have to be balanced since there’s no motion of the crate with respect to the truck. It’s not moving with respect to the truck, but with...

I drew a free body diagram for the crate. I have normal force going up, weight down, static friction force to the left and the force of the crate sliding to the right. I'm assuming the truck is moving to the left. I have Fnet=0 because the crate is not moving, so the forces are balanced. I...
