Thanks for the replies.
I understand the first free body diagram, but I don't have a clue about what to find first.
Also is there an applied force on the ball while it is in the air?
Two people kick a soccer ball at the same time. One person with a force of 100 N [N 25 degrees W]. The result is the ball moving 200m/s^2 [S 15 degrees W]. With what force did the second person kick the ball.
I'm not sure how to do this question, any help is appreciated greatly.
Thanks in...
