Question

give one example of a situation in which a body has a certain average speed but its average velocity is zero ? and explain it .

Its urgent ...

Answer 1

dekho bhai baat to badi suni hui si lag thi hai.....mei jab 9th mei tha TB ek question kiya tha aisa same to same........abhi tumhe solution de deta Hun smart wala.......

dekho.......speed is the ratio of total distance traveled to total time taken.......this speed is determined for total journey so it is also called average speed.......when a man starts from any point on a circle towards the circumference of circle.....he travels whole path of 2πr and returns original position.....so for this situation he has traveled complete distance with any speed .........in this situation the speed is a non zero quantity because both distance and time are non zero...........

but we know that displacement is the shortest distance between initial and final point.....and velocity is the ratio of displacement to time......so in the above situation the man returns back to original position.......hence his initial and final point is the same making displacement zero.......so for this....his average velocity = 0/ time = zero
