Question

A car goes from point a to b and then come back from b to a . What is displacement and average velocity

Answer 1

the displacement will be 0 as it came back to its initial place

Answer 2

The displacement is 0 as it starts from point a and comes back again to a
average velocity = total displacement/total time
here displacement= 0
and Time = x
so V average = 0/x =0 m/s
