since the distance
s = vt + 1/2 at^2,
4780*525 + 525^2/2 ax = 3.54*10^6
8850*525 + 525^2/2 ay = 7.77*10^6
On a spacecraft, two engines are turned on for 525 s at a moment when the velocity of the craft has x and y components of v0x = 4780 m/s and v0y = 8850 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 3.54 x 106 m and y = 7.77 x 106 m. Find the (a) x and (b) y components of the craft's acceleration.
