Question

Please urgent........​

Answer 1

Answer:

Average velocity of person is = 2 m/sec.

Explanation:

Half of revolution = 1/2 of 40 = 20

Average velocity = 40/20 = 2 m/sec.

Answer 2

Answer:2 m/s

Explanation:

The average velocity of the cyclist is 2 m/s

Displacement of the cyclist in half revolution is (d) which is equal to “diameter of the circular track”.

i.e., d = 80 m

Time taken, t = 40 s

“Average velocity” is defined as the ratio of the total displacement and the total time.

Average velocity (v)  =TOTAL DISPLACEMENT/TIME TAKEN.

                                   =80/40=2m/s

hope it helps...........

thank you.
