Answer:
a.x component of acceleration of craft=
b.y component of acceleration of craft=
Explanation:
We are given that two engines are turned on for 763 s.
x component of initial velocity of craft=
y component of initial velocity of craft=
After firing,
x component of displacement of craft=
y component of displacement of craft=
We know that velocity=
x component of final velocity of craft= 
y component of final velocity of craft=
We know that acceleration =
a.x component of acceleration of craft=
b.y component of acceleration of craft=
