On a spacecraft, two engines are turned on for 702 s at a moment when the velocity of the craft has x and y components of velocity v0x = 3290 m/s and v0y = 5105 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 4.00 106 m and y = 6.60 106 m. Find the x and y components of the craft's acceleration.
