Question 18 Correct Two runners start simultaneously from the same point on a circular 200-m track and run in the same direction. One runs m/s and the other runs at a constant speed of 5.50 m/s at a constant speed of 6.20 Part B How far from the starting point will each have run at that instant? d= 171 m Submit My Answers Give Up All attempts used; correct answer displayed Part C When will the fast one overtake the slower one for the second time? t- 286 Submit My Answers Give Up Incorrect Try Again; 2 attempts remaining Part D How far from the starting point will they be at that instant? 2

Explanation / Answer

for fist time overtake it take 285.71sec

part b so distance travel in 285.71 sec=285.71*6.2=1771.402m

so it is round circle of 200m so it meat at 1771.402/200=8.85701 means after 8 round on

0.85701*200=171.402m away from starting point

part c

so for second time overtake it take 2*285.71=571.428sec

part d

it will be 171.402*2=342.804 but it in cicular motion so 342.804-200=142.804m away from strating

answere 142.80m
