a man on a bicycle travels at a constant speed in the positive direction for a short time. He then stops for a short rest before returning back to his starting point at the same constant speed that he originally moved. Sketch a distance-tine graph and a velocity-time graph to represent this motion.
Answers
Answer:
Distance-time graph:
The distance-time graph will be a sawtooth graph, with a straight line representing the man's motion at a constant speed in the positive direction, followed by a flat line representing the time he spent resting, and then a second straight line representing the man's motion at a constant speed in the negative direction back to his starting point.
Velocity-time graph:
The velocity-time graph will be a step graph, with a flat line representing the man's rest, followed by two steps representing the acceleration and deceleration of the man as he starts and stops his motion. The first step will be a positive step, representing the acceleration of the man as he moves in the positive direction, and the second step will be a negative step, representing the deceleration of the man as he moves in the negative direction.
