Would someone please be able to help me with this question?

A particle moves in two dimensions with constant acceleration. Initially it has position vector 3i+2j m and velocity i+ j m/s . After 4 seconds it has position vector 7i- 4j m. What is its velocity at that time?

S = ?
U = ?
V = ?
A = ?
T = ?

Which of these do you know for this motion? Or if you are more used to a formula involving 'r' let us know.
