In the given arrangement, the rod is free to rotate about the hinge and it is in constant contact with the equilateral triangular block of base length `(2a)/(sqrt3)`. If the block is moving horizontally with a speed `upsilon = 20 ms^(-1)`, then find the magnitude of the angular velocity of the rod (in rad. `s^(-1)`)at the instant when `theta = 30^(@)`. [Given that `a = 1m]`
