A rigid rod is sliding. At some instant position of the rod is as shown in the figure. End $A$ has constant velocity $v_0$. At $t = 0, y = l$ .

AGraph of '$y$' as a function of time is a parabola.

BVelocity of end $B$ along the length of the rod is $\frac{{{v_0}y}}{{\sqrt {{x^2} + {y^2}} }}$

CGraph of $y$ as a function of time is an ellipse

DAngular velocity of rod is consatnt

Solution

$y^{2}+\left(v_{0} t\right)^{2}=\ell^{2}$
$\frac{y^{2}}{\ell^{2}}+\frac{t^{2}}{\left(\frac{\ell}{v_{0}}\right)^{2}}=1$
