Here is a question I had to figure out in my grade 11 physics class. "If a 40 kg child is running at a rope suspended from the branch of a tree at 8.0 m/s, and then jumps and grabs it, how high will he swing off the ground?" (I had to translate it so pardon me if it is hard to understand) One of my friends suggested doing Height=(M)/(V)/(A) but he has a habit of messing up. I would appreciate any help from anyone. Thx.
