A couple of soccer balls of equal mass are kiched off the ground at the same speed but at different angles. Soccer ball A is kicked off at an angle slightly above the horizontak, whereas boll B is kicked slightly below the vertical. How do each of the following compare for ball Aand ball B?

PHysics ONLY question 2 b) so what I would like you to do is read the questions and read the feedback and fix my answers thats all here is the question : Here is the feedback : You still did not take into consideration that the combined masses are moving when the spring is compressed. Find speed of combined mass at maximum compression using Momentum equation PTI = PTF and then use Energy Equations to solve for the spring constant. Ek1 + Ek2 = EkT + EE Where EE is the elastic energy stored in the spring. Then use EE = 0.5kx2 to solve for k here is my answer : fix it correctly and give me the final answer :
