A uniform rod AB of length 1m and mass 4kg is sliding along two mutually perpendicular frictionless walls OX and OY. The velocity of the two ends of the rod A and B are 3 m/s and 4 m/s respectively, as shown in the figure. Then which of the following statement(s) is/are correct?

Options:(select one or more)

Answer:

A, B, D

Solution:

Get $θ$ $3 cos θ = 4 sin θ$ $ω = \frac{3 sin θ + 4 sin θ}{ℓ} (KE)_{rotation} = \frac{1}{2} \frac{1}{12} ml^{2} ω^{2} = \frac{25}{6}$
