Homework Help: Physics

Posted by Bonnie on Friday, February 3, 2012 at 1:16am.

On a spacecraft, two engines are turned on for 666 s at a moment when the velocity of the craft has x and y components of velocity V0x = 3485 m/s and V0y = 5690 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 4.48 * 10^6 m and y = 6.96 * 10^6 m. Find the x and y components of the craft's acceleration.

So far, I tried this:
Vx = Vox + AxT
so Ax = (Vx-Vox)/T

so... Ax = (4.48*10^6 m - 3485 m/s)/666
Ax = 6721.494

But it says this is incorrect. What am I doing wrong? Please help!
