Question

car travel from A to B at 40 metre per second from B to a at 60 metre per second calculate the average speed and average velocity​

Answer 1

Answer:

Average speed = 2V1V2 / V1 + V2 

 = 2 x 60 x 40/ 60+40

 = 4800/100

 = 48 m/s

Average velocity = Total displacement / Total time = 0  (Since the body returns to its initial position, Total  displacement = 0)

Answer 2

Explanation:

Average velocity = .. 40+60/(A to B )+(B to A)

= 100/2

= 50 ans.
