(a) At a football game, imagine the line of scrimmage is the y'axis. A player, starting at the yaaxis, runs 7.50 yards, back (in the axidirection), then 15.0 yards parallel to the y'axis (in the iyadirection). He then throws the football straight downeld 40.0 yards in a direction perpendicular to the y'axis (in the +Xadirection). What is the magnitude of the displacement (in yards) of the ball? :st (b) What if? The receiver that catches the football travels 62.0 additional yards at an angle of 450 counterclockwise from the +xaxis away from the quarterback's position and scores a touchdown. What is the magnitude of the football's total displacement (in yards) from where the quarterback took the ball to the end of the receiver's run
