    I understand it, thanks mate! :D

    Kicking a Ball Upwards with force x and mass y

    I got 2.5m/s. I don't quite understand this part though, can you elaborate a little? What do the variables stand for in that equation? Is the equation just a derivative of ke = 1/2mv^2? Also, what do you mean with last line? Thanks.

    Kicking a Ball Upwards with force x and mass y

    Yeah, I got told that too... so if I just assume the amoutn of time the foot is in contact with the ball to be 0.1s, then I can do it. Thanks for your input, I really appreciate it :) I'll try and solve it now and I'll post back results

    Kicking a Ball Upwards with force x and mass y

    Homework Statement Problem (this is an extra credit challenge kinda thing): You kick a 2kg ball with 50N of force, directly upwards. The ball is not moving when you kick it. How far does it go and how long is it in the air (take gravity into consideration)? Homework Equations I don't know...
