Ahhh! I've seen some examples of this type of problem but I can't seem to solve it!
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 6.86 m. The stones are thrown with the same speed of 9.78 m/s. Find the location (above the base of the cliff) of the point where the stones cross paths.

I will be happy to check your work. The meeting place occurs at the same time t, and at the same finalaltitude hf.
