Homework Help: Projectile motion golf ball question

  1. Sep 25, 2005 #1
    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?

    For maximum distance with negligible air resistance, the best launch angle is 45 degrees. break down your [itex] \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
