Sir i have problem in finding velocity of center and trajectory of center. Is there any shortcut to find velocity of center.

By rigid body constraints

$u \sin θ = v \cos θ \Rightarrow v = u \tan θ V e l o c i t y o f c e n t r e o f m a s s = [u (- \hat{j}) + u \tan θ (\hat{i})] / 2 L e t c e n t r e o f r o d i s (x, y) \Rightarrow {(2 x)}^{2} + {(2 y)}^{2} = L^{2}$
