A bullet is moving horizontally with certain velocity. It pierces two paper discs rotating coaxially with angular speed ω separated by a distance l. If the hole made by bullet on second disc is shifted by an angle θ with respect to the first, find velocity of bullet.
(A) ωl
(B) \(\frac{lθ}{ω}\)(θ)2
(C) ω\(\frac{l}{θ}\)
(D) ωl
