Physics... Projectile Motion?

I don't know how to figure this out! It didn't tell you the time, yet you only know the distance(?). How do I figure this out?

Question: A boy on a 5-m tall tower throws a ball horizontally. The ball lands 20 meters downrange. What is his pitching speed?

And I have another question.

Question: A cannon is fired at an angle of 80 degrees above the horizontal. It's vertical component of velocity is 200m/s and it's horizontal component of velocity is 50m/s. Assume no air resistance.

A) How much time will it take the projectile (cannonball) to reach its maximum height?
B) How far horizontally will the cannonball travel?


Clearly, I'm not the brightest in Physics, and to some, these questions are WAY TOO EASY. But I still don't get it...? Help please!!!
