Bro it also can done by using 2πr first 6 1/2 rounds is eqal to 140 sec πr2x1/200 we get r = 100 take common from (2xπr)(πr) common is =πr. And 6 1/2 is now eqal to 7 Now put only πr from common 7x22/7x100 = 2200 And the displacement is eqal to =0 Because only half of circle is coverd

Kapil Kumar 1 year, 3 months ago

1min = 60sec 2min = 120sec + 20sec = 140sec Circumference = 200m Time taken for 1 round = 40s A.T.Q, 1 ROUND = 40sec 2 ROUND = (40+40)sec =80 sec 3 ROUND = (40+40+40)sec = 120 sec {140sec - 120sec = 20sec} 1/2 ROUND = 20 sec So,,,,, *DISTANCE* (1+2+3+1/2) round =200+200+200+200/2 =200+200+200+100 =700m Then,,,,, Displacement u = 0 v = 100 So displacement will be 100 m as he travelled 3.5 rounds so for 3 rounds displacement will be zero but for the half round displacement will be 100m Thanks 🙏
