question 47

Multiple Choice

A thin uniform rod (length = 75.0 cm,mass = 1.0 kg) is pivoted about a horizontal frictionless pin through one end of the rod.The moment of inertia of the rod through this axis is (1/3) mL².The rod is released when it is below the horizontal and it makes the angle $\theta$ with the horizontal.If the angular acceleration of the rod at the instant it is released is 15.0 rad/s²,what is the angle $\theta$ ?

• B)40 \(\circ\)
• C)20 \(\circ\)
• D)70 \(\circ\)
• E)60 \(\circ\)
