1. The problem statement, all variables and given/known data A quarterback takes the ball from the line of scrimmage and runs backwards for 1.0 x 10 ^1 m then sideways parallel to the line of scrimmage for 15 m. The ball is thrown forward 5.0 x 10^1 m perpendicular the line of scrimmage. The receiver is tackled immediately. How far is the football displaced from its original position? 2. Relevant equations well I convert change the sci into 10m and 50m 3. The attempt at a solution I don't know what kind of problem this is? what is it dealing with? yeah I'm looking for the displacement, but I thought displacement was just the difference from where it was at first... but well I have the answer which is 43m, but how in the world do I get to that number? and I'm so sorry for asking soo many questions, but I'm really lost and I have my mid term tomorrow. I know the rest but all these questions that I've been asking which were like mid through the semester. thanks to all who have been helping.
