In the figure given below the two masses were moving same velocity v in same direction and the spring is in its natural length. An impulse J = 2mv is given towards left to mass A. Then how many of given statements are correct. ( The ground is smooth and the spring constant is k.) B m A m (1) Mass A stops and Mass B continues to move. (II) The velocity of masses w.r.t centre of mass change with time after the impulse is given to block A. (III) The masses oscillate about a fixed point with T = 2π (IV) Amplitude of oscillation of masses is, A = v (a) 1 (b) 2 (c) 3 (d) 4
