I keep getting the wrong answer for this problem... can anyone help? On a spacecraft two engines fire for a time of 894 s. One gives the craft an acceleration in the x direction of ax = 5.67 m/s2, while the other produces an acceleration in the y direction of ay = 9.96 m/s2. At the end of the firing period, the craft has velocity components of vx = 5920 m/s and vy = 9410 m/s. Find (a) the magnitude...
