On a spacecraft, two engines are turned on for 730 s at a moment when the velocity of the craft has x and y components of velocity v0x = 4040 m/s and v0y = 6110 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 5.08 106 m and y = 7.20 106 m. Find the x and y components of the craft's acceleration. ax = m/s2 ay = m/s2.
