Bhaiya can u xplain it plsssss????

the velocities at both ends should be same in order to move the rod so the cosine of 3 ie 3cos60 is the velocity at upper portion (min)

velocity of all the points of the rod along the length of the rod is same since it is a rigid rod and can neither contract or expand.

vel. of lower end along the length of the rod is 3.cos60 . since the rod is rigid, min. vel of upper end will be 1.5 m/s
