Question

An athelete completes one round of a circular track of diameter 49 m in 20 s. Calculate the distance covered and displacement at the end of 50 s.​

Answer 1

Answer:

Your Answer

Distance Covered = 122.5 m

Steps - 49 m in 20 seconds the how much in 50 sec so...

= 49 × 50 / 20 ( cross multiplication )

= 122.5 m

Displacement = 24.5 m

Steps - After 40 Sec Displacement would be 0 because athletes will come at point from were he started but in next 10 sec he will cover 24.5 m because he covers 49 m in 20 sec so he would cover 24.5 m in 10 sec ( half )
