Question

An athlete completes one round of a circular track of radius 'R' in 30 seconds.calculate distance travelled and displacement in 45 seconds​

Answer 1

Answer:

distance is 3πR...

displacement is πR

Step-by-step explanation:

if in 30 sec he covers 2πR

in 1 sec he will cover 2πR/30

so in 45 sec he will cover 3πR...

and displacemet is equal to final minus initial...so 3πR minus 2πR gives πR..
