Calculate speed and height in given time for motion

  1. Sep 27, 2013 #1
    Hello All,

    Unfortunately I'm pretty bad in physics, so I would like to ask from you.

    I have two problems:

    1.

    I have a ball. The soccer kick the ball in a given angle, and I would like to find out what is the speed and height of the ball. Is there any equation or function what can I use for it?

    2.

    How can I calculate the force of the kick if I know how far the ball should be kicked?


    Thank you

    2. You can't calculate the force. But you can calculate the impulse which is the average force times the time interval during which the force was acting. You don't know what that time interval is so it is not possible to calculate the force.
