Two football players are initially 2m apart. At the same instant they accelerate towards each other, each at different constant accelerations until they collide. Graph the motion (from your inertial point of view (you are in the stands)).
a) Draw position, velocity and acceleration graphs for this question.
b) Draw a picture. Define your coordinate system.
