A machine has an 760g steel shuttle that is pulled along a square steel rail by an elastic cord . The shuttle is released when the elastic cord has 16.0N tension at a 45º angle. What is the initial acceleration of the shuttle?

Here is the only photo associated with this problem:knight_Figure_05_59.jpg [Broken]

Now I think the only equations necessary are [tex]\Sigma[/tex]F_x = n_x + T_x + F_Gx + f_kx = ma_x and [tex]\Sigma[/tex]F_y = n_y + T_y +F_Gy + f_ky = ma_y.

I thought that I could use those two equations in tandem and use the values for a_x and a_y as the a and b sides of a the right triangle whose hypotanuse of which is the answer to the problem and lies along the cord that pulls the shuttle.
