Question

Two particles $A$ and $B$ are connected by a rigid $\operatorname{rod} A B$. The rod slides along perpendicular rails as shown here. The velocity of $A$ to the left is $10 \mathrm{~m} / \mathrm{s}$.\ What is the velocity of $B$ when angle $\alpha=60^{\circ}$ ?\

Professor PC Thomas Classes · Answer

(d) : Let particle $B$ move upwards with velocity $v$, then $	an 60^{\circ}=\frac{v}{10} ; v=\sqrt{3} 	imes 10=17.3 \mathrm{~m} / \mathrm{s}$.\
