Split this into two problems. Since the projectile starts horizontal it keeps its horizontal speed. There is no horizontal force to change that speed.
On the other hand it starts with no vertical speed but there is a vertical force, gravity. Therefore it accelerates down at 9.8 m/s^2
A) is just a falling problem
h = (1/2) g t^2
620 = 4.9 t^2
t = 11.25 seconds
B) It goes for 11.25 seconds at 220 m/s
11.25*220 = 2475
thank you soooooo much(:
