1. An athlete completes one round of a circular track of diameter
200 m in 40 s. What will be the distance covered and the
displacement at the end of 2 minutes 20 s?
Answers
Answer:
Given that
Given thatDiameter of circular track = 200 m
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 m
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to find
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/Time
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πr
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 seconds
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 secondsNumber of rounds = 140/4 = 35
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 secondsNumber of rounds = 140/4 = 35= Distance covered = 35 × circumference
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 secondsNumber of rounds = 140/4 = 35= Distance covered = 35 × circumference= Distance covered = 35 × 2 × 22/7 × 100
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 secondsNumber of rounds = 140/4 = 35= Distance covered = 35 × circumference= Distance covered = 35 × 2 × 22/7 × 100= Distance covered = 5 × 2 × 22 × 100
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 secondsNumber of rounds = 140/4 = 35= Distance covered = 35 × circumference= Distance covered = 35 × 2 × 22/7 × 100= Distance covered = 5 × 2 × 22 × 100= Distance covered = 22000 m
Given thatDiameter of circular track = 200 mRadius, r = 200/2 = 100 mTime is taken by an athlete to complete one round = 40 seconds.We have to findDistance covered = ??Displacement = ??Formula to be used :-Speed = Distance/TimeCircumference of circle = 2πrSolution :-2 min 20 seconds = 140 secondsNumber of rounds = 140/4 = 35= Distance covered = 35 × circumference= Distance covered = 35 × 2 × 22/7 × 100= Distance covered = 5 × 2 × 22 × 100= Distance covered = 22000 mHence, the distance covered at the end of 2 min 20 seconds is 22000 m or 22 km.
