   This will probably be moved to the homework section, this is not a forum to discuss school exercises.
   
   Surely you have spent sometime doing constant acceleration in one dimension. This problem is not much more difficult then those, except that we have two independent directions, and so we can write the equation for constant acceleration in the x-direction and seperately write the equation for constant acceleration in the y-direction.
