An athlete completes one round of circular track of diameter 14m in 20...
Distance Covered and Displacement Calculation:
- To calculate the distance covered in 2 minutes and 10 seconds, we first need to find out how many rounds the athlete completes in this time duration.
- Since the athlete completes one round in 20 seconds, in 2 minutes and 10 seconds (i.e., 130 seconds), the athlete would complete 130/20 = 6.5 rounds.
- Now, the total distance covered by the athlete in this time duration would be 6.5 times the circumference of the circular track.
- The circumference of a circle can be calculated using the formula: Circumference = π * diameter.
- Given that the diameter of the track is 14m, the circumference would be 3.14 * 14 = 43.96m.
- Therefore, the distance covered by the athlete in 2 minutes and 10 seconds would be 6.5 * 43.96 = 285.74m.
Displacement Calculation:
- Displacement is the shortest distance between the initial and final position of the athlete.
- Since the athlete completes multiple rounds, the displacement at the end of 2 minutes and 10 seconds would be the distance between the starting point and the point where the athlete finishes the last round.
- The athlete will end up at the starting point, so the displacement would be zero.
Therefore, at the end of 2 minutes and 10 seconds, the athlete would have covered a distance of 285.74m and the displacement would be zero.
