Homework Help: AP Physics need helpz0rz w/ 1 problem

  1. Sep 26, 2004 #1
    ok ive been trying to figure out this problem for about an hour :/

    A golfer drives a ball at an angle of 30 degrees with the horizontal at an initial speed of 60m/sec. How high does the ball rise?

    ok im pretty sure this is a projectile problem.
    Vf=0(?)
    Vh=52m/s
    Vv=30m/s (i used sin and cos to get those 2 components)
    g=-9.8m/s^2

    I tried figuring out the time for the vertical. So, I did Vf=Vi+at. 0=30+(-9.8)t. t=3.06s. Then I tried finding the height using v=d/t. 30m/s=d/3.06. I ended up getting the wrong problem..the real answer is 45.9m.

    I could realllly use some help :/
