Two stones are thrown simultaneously, one straight upward from the base of a cliff and the other straight downward from the top of the cliff. The height of the cliff is 6.80 m. The stones are thrown with the same speed of 9.05 m/s. Find the location (above the base of the cliff) of the point where the stones cross paths.

Stuck on this concept thanks!
