Maximum Horizontal Distance for Flea Jumping

[poiuytrtyuiop]

Hi,

I am not sure how to go about this problem. Any help would be very appreciated.

A flea can jump a vertical height h. What is the maximum horizontal distance it can jump?

Thank you.

hmmm... I'm not sure but I know that it has something to do with the angle at which the flea jumps because if it jumps at a 45 degree angle he will go much further than if he jumped at a 10 degree angle.

The problem is going to involve some assumptions on how the flea propels itself.
