I have one more physics question?
At what velocity must you launch a pumpkin from a cannon such that when your friend standing at the top of a 565m deep canyon can catch it a 0m/s velocity?

This is a very poorly written question. The only way the pumpkin would have both vertical and horizontal velocity = 0 is at the peak height of a perfectly vertical trajectory.
Vf² = Vi²+2*a*h = 0² = Vi² - 2*9.8*565
Vi² = 19.6*565 = 105²
Vi = 105m/s
