Answer to Question #152143 in Mechanics | Relativity for Bipin Bashyal

Question

A racing car moving along a circular track of radius 'r' at constant speed 'v' has described the angle 'a' at the centre of track. What is the average velocity?

Answer 1

Answer

Total displacement =a

Total time taken to travell this displacement

$T=\frac {\pi a }{3v}$

So average velocity

$v_a=\frac{displacement}{time}$

average velocity

$=\frac{3v}{\pi}$
