on
a spacecraft, two engines are turned on for 687 s at a moment when
the velocity of the craft has x and y components v0x= 3250 m/s and
v0y=5740 m/s. while the engines are firing the craft undergoes a
displacement that has components of x=2.91x10^6 m and y=5.46x10^6
m. find the a (x) and b (y) components of the crafts
acceleration?
