I don't understand those problems. I need help solving them.

1. A projectile is launched at an angle of 26 with an initial velocity of 120 m/s. A) What is its total time in the air? B) What is its maximum altitude? C) How far does it travel horizontally? 2. A ball is thrown horizontally from the top of a 5 m high building. The ball lands 28 m from the base of the building. What was its launch velocity? 3. A ball is thrown straight up with an initial velocity of 26 m/s. A) What is the ball's maximum height? B) What is the total time the ball is in the air for? C) What is the ball's velocity 1.5 seconds after launch
