Answer 2

Answer:

see if it completes a track of 100 m diameter in 15 seconds....then that means it completes the whole circular track in 15 seconds..!!

now the circumference of track is given by 2pir(pi=22/7)... now if u out the values the answer we get is 314 m...! now it says how much is the displacement at the end of 3 minutes and 30 seconds...we know that It covered the whole circle in 15 seconds ..then we would check out where is this athlete is after 3 minutes and 30 seconds..!!

the answer is this guys is at that same point to which it has started ...so the displacement would be zero..!!

I hope u got that ...
