On a spacecraft two engines fire for a time of 589 s. One gives the craft an acceleration in the x direction of ax = 5.09 m/s2, while the other produces an acceleration in the y direction of ay = 7.50 m/s2. At the end of the firing period, the craft has velocity components of vx = 3781 m/s and vy = 4857 m/s. Calculate the magnitude of the initial velocity.

Vf=Vi+at
solve for Vi. Do this in vector form, ie, i,j components of acceleration. Then Vi will have both components.
