In a long distance race, the athletes was expected to take four rounds of the track such that the line of finish was same as the line of start. Suppose the length of the track was 400 m. (i) What is the total distance to be covered by the athletes? (ii) What is the displacement of the athletes when they touch the finish line? (iii) Is the motion of the athlete uniform or non uniform? (iv) Is the displacement of an athlete and the distance moved by him at the end of the race equal?
Answers
Answer:
Explanation:In the first case the total length of the field is 400 m and athlete run 4 rounds of it So 4×400= 1600.
In the second case the displacement is zero because the athlete initial position and the final position is same so initial position minus final position is equal to 0. In the third case the motion of athlete is non-uniform or maybe uniform because the athlete maybe tired by four rounds. In the fourth case that displacement is zero and the distance moved by athlete is 400 so the statement is wrong because they do not race equal.
Answer: 1》4 × 400
2》0
3》4 round
4》displacement is 0 and distance is 400
Explanation: thank you and have a nice day
