Homework Help: Projectile Motion(difficulty level-7)

  1. Jan 24, 2005 #1
    A football is kicked at an angle of 50 degrees and travels a distance of 20 m before hitting the ground.

    What is the initial speed of the ball? (14.1 m/s)
    How long is it in flight? (2.2 sec)
    How high does it rise? (5.94 m)

    I have the answers but I don't know where to go with the information that is given. If anyone could help explain this problem, it would be greatly appreciated! Thanks!
