# Two dimensional motion with constant acceleration question

I have this question but I am struggling to answer it any help would be greatly appreciated!

An object is moving in a plane. At time t=0 it is at the origin, O, and moving with velocity U. After two seconds, it is at A, where OA = -2i-4j. After a further three seconds, it is at B, where AB =10I-40J. Assuming the object has constant acceleration a, work out a and u.

The acceleration is a vector and the forces in perpendicular directions act independently. So solve for i and j seperately (using suvat in each direction).
