A verical thin rod is hinged at point P, due to slight push rod starts to rotate.The velocity of centre of mass of rod just after turning angle 0 is [L is length of rod] (## AAK_TST_09_NEET_19_PHY_E09_041_Q001 ##)

Two blocks A and B having masses 5 kg and 10 kg respectively connected through a massless string which is passing over a pulley (disc) of mass 2 kg and radius 25 cm as shown in figure If system is. released from rest. then angular acceleration of the pulley is (String does not slip over the pulley horizontal surface is smooth and g = 10ms ^-2 (AAK_TST_02_NEET_PHY_E02_011_Q01)

A particle of mass 2 kg released from point A(2, 0, 0) m as shown in the figure. The rate of change of angular momentum of the particle about the origin at time t = 2 s will be (Origin is taken somewhere above the ground in space at sufficient height and g = -10 hat j m/s^2 ) (AAK_TST_02_NEET_PHY_E02_016_Q01)
