Question

can someone please help me for this?​

Answer 1

Explanation:

diameter of the circle = 200m

time taken to complete one round = 40 s

2 minutes and 40 s = 160 s

time taken for one round = 40 s

tine taken for 2 rounds = 80 s

time for 3 rounds = 120 s

tine taken for 4 rounds = 160 S

therefore he will take 4 rounds in 160 s

the displacement at the end of 2 mins and 40 s will be 0 as he comes back to his initial position
