[QUOTE="omar1, post: 4872620, member: 454410"] Ok, I'm having some difficulty with a problem. It just doesn't add up. [B] 1. Homework Statement [/B] Consider a 2.4kg ball and a 12.4kg ball in free fall. A) Find the Force that is acting on each ball. B) Find the acceleration of each ball, given Earth's gravity of 9.80 m/s/s.[h2]Homework Equations[/h2] [tex]\omega = mg[/tex] [tex]F=ma => a=\frac{F}{m}[/tex] [h2]The Attempt at a Solution[/h2] Forumla: F[SUB]1[/SUB]=23.52[B]N[/B] F[SUB]2[/SUB]=121.52[B]N[/B][tex]\frac{23.52N}{2.4kg}= 9.80\frac{m}{s^2}[/tex] [tex]\frac{121.52N}{12.4kg}= 9.80\frac{m}{s^2}[/tex] I've solved the Force, part A, but the acceleration, part B, is making me crazier. I come out with g (9.8m/s2), this can't be correct!? So I think I must be missing a Kinematics formula, but I have neither velocity or time to work with. The ball has a weight, so the acceleration of both balls must be faster than gravity? Correct?Any help in the right direction would be appreciated. Thanks! [/QUOTE]
