Question

Derive the formula or explain how the formula come that is v =2pie r/t​

Answer 1

Step-by-step explanation:

As we know velocity= Displacement/time

when the displacement is around a circle.. then it is equal to it's circumference i.e 2 pie r

the time period for completing a revolution is 't'

hence... by substituting the values..formula becomes :

v= displacement/time = 2 pie r/t
