Find the cart's speed one quarter of a loop later (when it's at the same height as the loop's center).

I know there is radial acceleration due to the change of the velocity vector around the circular path, but how do I know the speed is changing? Also how can I determine what the speed will be at that exact point along the circular path? Any help is appreciated! I'm really confused on how to set up this problem
