Question

a body travels from A to b 40m and B to A 60 m .Find the average speed and velocity

Answer 1

Hii
here is ur answer

average speed=total path length/Time interval

time=distance/velocity
t1 =AB/40
t2=AB/60
t1+t2=AB/40+AB/60
=AB/24

average speed=2AB/AB/24
=2/1/24=48m/s

average velocity=displacement/time taken

the body moves from A to B and then B to A
so displacement is 0

therefore average velocity=0m/s

hope it helps you

thank you

Answer 2

Hey there !

Solution:

Given :

Distance Travelled = 40 m to 60 m

=> Distance Traveled = 60 m + 40 m = 100 m

Displacement = 0

As the body returned to the original position.

Average Speed = Total Distance / Total Time

=> Average speed = 100 m / Time

Since Time is not given I am giving the solution in terms of time itself.

Therefore Average Speed is 100 m per unit time.

Average Velocity = Displacement / Time

Displacement = 0. Hence,

Average Velocity = 0 / Time

We know that 0 divided by anything is 0.

Hence Average Velocity = 0 m/s

Hope my answer helped !
