All the physics problems I have worked with thus far assume stating and ending at the same height. Any help is how to solve this is appreciated :-)

A baseball player throws a ball from height 1.5 meters at an angle of 30 degrees and an initial velocity of 20 m/s. He is trying to hit a pole 20 meters away which is 1.7 m tall. Forget about air drag, etc*how long does it take the ball to travel 20 meters (in the horizontal)

*what is the height of the ball when it reaches the pole?

*what is the final velocity of the ball?

*what is the final angle (assuming the ground is perfectly flat of course)

To find the time does this sound right?: t = (20meters)/(20m/s * cos (30))

This is where I am stuck... I would think height at 20 m is just the y component analyzed at 20 but I'm not sure about that. The final velocity I have not idea on and the final angle would probably be the sum of the x and y components although I don't know how to manipulate the formuli to get that :-( Any help is greatly appreciated :-)
