this problem we have to find How much work did the ball do on the wall? So we know that net work them on the system is a call to change. In kinetic energy, that means K a final minus K initial. It's okay. A finalist half and the final square, minus half m. We initially square so we can buy it. It is half into em. We finally square minus. We initially square. So this is the work done this half into Mars, which is to gauge e into the finalists. Tennis squared minus V initialism minus 20 square. Now we will solve this. This is a whole new mhm 100 minus 400. This is called a minus 300 jewels. This is that work done by the wall on the wall. If we check options, options, even we correct option. Option A. Yes, correct. Yes. Thank you.
