It's Blocking The Home Run!

Classical Mechanics Level 5

A Baseball player is ready to hit a Home Run. But, he notices a wall, which is at a distance \(\displaystyle L\) meters from him, standing \(\displaystyle H\) meters high.

This player turns out to be the laziest player in the team, but nonetheless very clever. He devices a situation where he can cross the wall with minimum effort (i.e with minimum initial speed).

Find this minimum speed \(\displaystyle u_{min}\).

Details and Assumptions:
\(\bullet\) \(\displaystyle L = 10m\)
\(\bullet\) \(\displaystyle H = 5m\)
\(\bullet\) Take \(\displaystyle g = 9.8m/s^2\)
