Two particles...

Question

Two particles each of mass m are connected by a string of length 1m. The particles are kept on a smooth horizontal plane. The initial separation between the particles is 0.5 m. One of the particles is given a velocity 18 m/s as shown. Find the magnitude of angular velocity of one particle with respect to the other particle just after the string becomes taut (in rad/s). ___

Solution

$∵ 18 s i n 30^{\circ} = ω r = ω \times 1 = ω = 9 r d / s$
