i came to class late and missed the lecture i want you to explain the problem for me i think it is already answered

please explain step by step

i think the problem is about a launcher you have to find the measurement

that is what the teacher sent us an email. i hope this hlep because i don’t have the question

Hello class, I think I loaded up the launcher to notch 3, instead of the 2 that we used to predict V. We will fire it again on Monday, to test our predictions.
