Question

A rigid rod of length 1 m1 \text{ m} is resting at an angle θ=45∘\theta = 45^\circ as shown in the figure. The end P is dragged with a velocity of U=5 m/sU = 5 \text{ m/s} to the right. At the instant shown, the magnitude of the velocity VV (in m/s\text{m/s}) of point Q as it moves along the wall without losing contact is
A rigid rod PQ of length 1m resting against a vertical wall (y-axis) and a horizontal floor (x-axis). Point Q is on the wall, point P is on the floor. The angle between the rod and the floor is $\theta = 45^\circ$. Velocity of P is $U = 5 \text{ m/s}$ to the right. Velocity of Q is $V$ downwards.
