A rod of length l lying horizontally on a smooth horizontal surface is moving with centre of mass velocity v and angular velocity ω=2vl. The distance covered by one of the end points of the rod during the time the rod completes one full rotation is nl. Find the value of n
Given,
Distance covered during one rotation is nl
Angulate velocity, ω=2ul
Angular velocity, ω=2πT⇒Tω=2π
Distance, S
S=vT=(lω2)T
⇒nl=l2×2π
⇒n=π
Hence, value of n is π .
