Projectile Motion daredevil

  1. Nov 17, 2008 #1
    1. The problem statement, all variables and given/known data
    A daredevil is shot out of a cannon at 45degrees horizontal with an initial speed of 25.0m/s. A net is positioned at a horizontal distance of 50m from the cannon from which it is shot. At what height above the cannon should the net be placed in order to catch the daredevil?


    2. Relevant equations

    P=X/ViCos(theta)


    3. The attempt at a solution
    i tried this equation but it did not work out. The answer is supposed to be 10.8m. Please explain it if you get this correct. Thank you!

    try this equation y = F(x): = yo +xTAN[tex]\theta[/tex] - gx2/2Vo2COS2[tex]\theta[/tex]
