  1. May 26, 2009 #1
    Question :
    A boy kicked a football with an initial velocity component of 15.0m/s and a horizontal velocity component of 22.0m/s.
    a)what is the velocity of the football(magnitude and direction)
    b)how much time is needed to reach the maximum height?

    (this is not my homework,it is a question which was not been discussed in class so I am not able to answer it.)

    Welcome to PF!

    Hi mohammed1992! Welcome to PF! :smile:

    (you mean "initial vertical component" :wink:)

    I assume you can do (a).

    For (b), you should have used the usual https://www.physicsforums.com/library.php?do=view_item&itemid=204" equations …

    show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:

    (same for your other thread :wink:)
