A spacecraft is traveling with a velocity of V0x=5480m/s along the+x direction. Two engines are turned on for a time of 842s.One engine gives the spacecraft an acceleration in the +x directionof ax=1.20m/s^2, while the other gives it an acceleration in the +ydirection of ay=8.40m/s^2. At the end of the firing, find Vx.
