Question

Which of the following graphs applies to each situation? Each graph shows the behaviour of two objects: east is in the direction of positive d. (E.g., if graph A applies to situation 1, and C to the rest, enter ACCCCC) 1) An upward moving elevator colliding with a downward moving elevator. 2) A jogger overtaking a walker. 3) A car, initially at rest, accelerating and a car moving initially at constant speed applying the brakes until it stops. 4) An initially moving truck speeding up eastward and a westward moving track slowing down. 5) A train, initially moving at a steady speed, has brakes applied to match the speed of a train on a parallel track. 6) An eastward moving track applying the brakes and a westward moving truck speeding up.
