Neha swims in a hundred metre long policy covers 200 metre in 1 minute and 40 seconds by swimming from one end to the other and back along the same straight path find the average speed and average velocity of Neha |
|
Answer» Answer: Explanation: LENGTH of pool = 100m total time taken = 1 min + 40s = 60s + 40s = 100s total DISTANCE covered by Neha = 200m therefore, the total displacement covered by Neha = 0M [because she swims from one end of the pool to the other and back along the same straight path, to her original position.] Now, According to the question- average speed = total distance = 200 m = 2 m/s total time taken 100 s average velocity = total displacement = 0 m = 0 m/s total time taken 100 s |
