Homework Help: PHYSICS HWK. Problem-Stuck?

  1. Sep 8, 2004 #1
    In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.050 s during which time it experiences an acceleration of 390 m/s2. The ball is launched at an angle of 54° above the ground. Determine the horizontal and vertical components of the launch velocity.

    vx = ? m/s
    vy = ? m/s

    I think this should be in the homework section.

    [tex] a = \frac{v - v_o}{t} [/tex]
    [tex] 390m/s^2 = \frac{v - 0m/s}{0.050s} [/tex]

    I think you know how to do the rest. If you dont, ask away.

    Personally, I wouldn't trust an answer given by anyone stupid enough to fall for that!
