Find the speed of an athelete who completes one lap of a circular track with radius 100m in 1 minute
Answers
Answer:
1.46 m/s
Explanation:
Radius = 100 m
thus, circumference of the circular track = 2πr
= 2 × 22/ 7 × 100 m
= 4400/7
= 628.57 m
therefore, Speed = Distance / Time
=628.57 m/ 60 secs
= 1.46 m/s
Answer:
Radius of circular track is r = 100m
So Circumference of the circular traack = 2πr
= 2 X 22/7 X 100 = 628.57
speed = distance / time
= 628.57m / 1 minute = 628.57m / 60 seconds
= 10.47 m/s.
