Projectile motion golf ball question

[11thgradephysics]

If the initial velocity of a golf ball is 30.3 m/s off the club face, and the tee box is at the same height as the green, what is the longest shot possible?
(not inlcuding roll)
i have no clue where to start please help?
all that i know is initial velocity and accelration due to gravity, so how do i solve?

This is a good bit of information to learn: for the maximum projectile distance, it needs to be launched at 45 degrees. Can you take it from there?

 

[whozum]

For maximum distance with negligible air resistance, the best launch angle is 45 degrees. break down your \vec{v_0} [/tex] vector into vertical and horizontal, and find the flight time to find the flight distance. For roll, you'll need a friction coefficient on the green/rough to see how far it will roll.

ahh, it nefver said in my book that max proj is 45 degrees, now i think i can do it
