Q27. A pendulum consists of a massive bob suspended firom a hook by an elastic band The spring constant k of theband and the mass m of the bob are such that k/m o 10 rad /s, and the unstretched length of the band is L = 1m. The pendulum is released from an angle from the vertical of 60 degree. Initially the speed of the bob is zero and the band is in a relaxed (unstretched) state. The total length of the band at the lowest point in the bob s trajectory 1s (a) 1.6 m 6) 2.6 m (C) 35 (d) 0.6 m
