12. A spacecraft is traveling with a velocity of v0x = 5480 m/s along the +x direction. Two engines are turned on for a time of 842 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.20 m/s2, while the other gives it an acceleration in the +y direction of

ay = 8.40 m/s2. At the end of the firing, find (a) vx and (b) vy.

 

Basic equation we need is

We just do it for each component so we get
