2d motion

  1. Sep 22, 2009 #1
    1. The problem statement, all variables and given/known data
    A golf ball with an initial angle of 33◦ lands ex-
    actly 184 m down the range on a level course.
    The acceleration of gravity is 9.81 m/s2 .
    a) Neglecting air friction, what initial speed
    would achieve this result? Answer in units of
    m/s.
    009 (part 2 of 2) 10.0 points
    b) Find the maximum height reached by the
    ball. Answer in units of m.


    2. Relevant equations
    acceleration formula




    3. The attempt at a solution

    I got A but cant get B.

    at the max height, the final vertical velocity =0

    to y=vxt -1/2gt^2
