I've been stuck with this problem for a while. Appreciate if anyone can point me in the right direction.

A boy stands in a field, he throws a stone with an initial 45 degree angle. The field has a 5 degree angle downwards, so the stone touches down at -5 degree angle and 82 meters away. g=9,8m/s^2

Find the time (t) for the entire throw, and the initial velocity (v0) for the stone.
