Question

A rod, pivoted at O , is resting on a block of height h . If the block moves with a constant velocity v , then the angular velocity of the rod, at the instant shown, is, v c o s 2 θ h, v t a n θ h, v s e c 2 θ h, v c o s θ h

MARKS App · Accepted Answer

t a n θ = x h ⇒ x = h t a n θ ∴ d x d t = h s e c 2 θ d θ d t ⇒ d θ d t = v h c o s 2 θ
