Relative motion
Classical Mechanics
Level 3
If block \(A\) is moving horizontally with velocity \(v_{A}\), then find the velocity of block \(B\) at the instant as shown.
\[\frac{hv_{A}}{\sqrt{x^2+h^2}}\]
\[\frac{xv_{A}}{2\sqrt{x^2+h^2}}\]
\[\frac{hv_{A}}{2\sqrt{x^2+h^2}}\]
\[\frac{xv_{A}}{\sqrt{x^2+h^2}}\]
