A player completes a circular path of radius r in 40s at the end of 2 min 20 sec find displacement |
|
Answer» As it takes 40s to complete one ROUND in 2 min 20 sec the player would be able to complete 3.5 rounds . Now try to imagine a player who has completed half of a round of a circle when you do that you will SEE that the SHORTEST path between the initial and the FINAL point is equal to the diameter . Thus , the displacement of the player is equal to 2r |
