Projectile motion

  1. Nov 30, 2006 #1
    1. The problem statement, all variables and given/known data

    An athlete puts a 16lbs shot at an angle of 45 degrees to horizontal from 6.5ft above the ground at initial speed of 44ft/sec. How far does the shot land?
    g=32ft/s^2



    2. Relevant equations

    I can only calculated the range from the point it is fired to the point where it is 6.5 ft from the ground. But I have no clue calculating the distance travelled from the interval where it is 6.5ft above the ground to the ground(y=0).

    3. The attempt at a solution

    d = V0^2 sin2(45)/(32)
    = (44)^2/ 32
    = 60.5 ft
    this is all i know. help please.

    You might want to write down all relevant equations for projectile motion and see what you can do with them.
