Final answer:
In a 100-meter running race, the distance and displacement are both 100 meters. The speed and acceleration of the runner would depend on the time taken to cover the 100 meters and changes in velocity, respectively. Typically, speed is calculated by dividing the distance by time and acceleration by the change in velocity over time.
Step-by-step explanation:
When someone is participating in a running race of hundred meters and goes from the starting point to the finishing point, the following can be determined:
- Distance: This is the total path length covered during motion. For a straight race from start to finish, the distance is 100 meters.
- Displacement: This is the straight line distance from the starting point to the finishing point in a specific direction. For a straight 100 meters race, the displacement is also 100 meters, pointing in the direction from start to finish.
- Speed: This is calculated by dividing the distance by the time taken to cover that distance. If it took 11.2 seconds for the winner to finish the race, the average speed would be 100 meters / 11.2 seconds, which is approximately 8.93 m/s.
- Acceleration: This is the rate of change of velocity. If the runner runs at a constant speed, acceleration would be zero. Otherwise, acceleration can be calculated by dividing the change in velocity by the time over which the change occurs.
The speed and acceleration specifics cannot be provided without additional information, such as the time taken to cover the 100 meters or any changes in velocity. In a typical 100 meters race, runners aim to maintain the highest constant speed possible, which would imply minimal acceleration after the start.
