1. The problem statement, all variables and given/known data Famous quarterback Fleet O. Floote is attempting a quarterback draw by running up the middle toward his goal line at 4.6 m/s. A linebacker hits him squarely, and their combined final velocity is 3.8 m/s at an angle of +120.° from the quarterback's original direction. The time it took to change direction at impact was 0.20s. Choose an appropiate horizontal coordinate system and calculate the average acceleration vector of the quarterback during the tackle. 2. Relevant equations a = ΔvΔt 3. The attempt at a solution v1 = 4.6 m/s 90.0° v2 = 3.7 m/s 120.° v1x = 0 m/s v1y = 4.6 m/s v2x = 3.7 cos 60° = 1.9 m/s v2y = 3.7 sin 60° = 3.2 m/s I have this, but I feel that I'm missing something.
