A football is kicked off with an initial speed of 63 ft/s at a projection angle of 45 degrees. A receiver on the goal line 67 yd away in the direction of the kick starts running to meet the ball at that instant. What must be his minimum speed (in feet/second) if he is to catch the ball before it hits the ground?

I've tried many different things and cannot figure this out. If anyone has time can you please walk me through this problem? It will help me on my others I have to do as well.
