Please do help me in this physics questions please. I promise to give a good feedback and perfect score.. Please i badly need it in 1 hour from now. This is already an answered equations/problems. All i need to know is to know if why is it kinetic energy etc. is indicated in here. And why the symbol in this particular parts is equals or plus and minus. Or a complete explanation on why this is my answer and where did i get it from. PLease, i do hope you could help me. I promise to give a perfect score as a feedback.
