A spacecraft is traveling with a velocity of v0x = 6570 m/s along the +x direction. Two engines are turned on for a time of 716 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.75 m/s2, while the other gives it an acceleration in the +y direction of ay = 8.99 m/s2. At the end of the firing, what is a) vx and b) vy?
