a person moves along the boundary of a square field of side 10m in 20 seconds . what will be the magnitude of displacement of that person at the end of 2 minutes 20 seconds?
Answers
Answer:
displacement =0 , speed =2 m/s and distance =40 m
displacement is shortest path between final and initial position . The person reach the initial position at last therefore displacement is 0 m.
Distance is total length traveled it 40 m as he moved one round against a square having length of one side 10 m.
speed is total distance divided by total time which is 40 divided by 20 m/s.
Explanation:
Answer:
displacement =0 , speed =2 m/s and distance =40 m
displacement is shortest path between final and initial position . The person reach the initial position at last therefore displacement is 0 m.
Distance is total length traveled it 40 m as he moved one round against a square having length of one side 10 m.
speed is total distance divided by total time which is 40 divided by 20 m/ss
