Question

A man swims in a 50 m long pool. He covers 100 m in one minute by swimming from one end to the other and back along the same straight path. Find the average velocity of the man​

Answer 1

ExplanatAverage velocity = Total displacement / Total time

                          = 0 / 60 sec = 0

velocity needs certain direction ,but here we can calculate speed but not velocity.

Answer 2

Given: length of swimming pool = 50m

Distance covered in one minute = 100m

To Find: The average velocity of the man

Solution:

The man covers 100m in one minute.

The man starts from a point in the pool and swims to the other point. He then returns to the same point. So he covers a distance of 50m while going and in the return also the distance covered is 50m.

As the man returns to the same point from where he started, his displacement will be zero.

Average velocity = Displacement / time taken

Average velocity = 0m/60secs

                            = 0

Therefore, the average velocity of the man will be 0.
