One end of a rod of length 5 m is hinged at a point of block A and other end is always in contact
with block B as shown below. Block A is pulled towards left with velocity 3 m/s. Then angular
velocity of rod in rad/s when rod makes an angle 37° from horizontal is:

3 m/s+
Two blocks having mass 6 kg and 3 kg respectively are moving on a smooth horizontal surface
towards each other with velocities 0.5 m/s and 1.5 m/s respectively massless spring of spring
2500 N/m are connected to both blocks as shown. The springs are at same horizontal
