MHT CET 2025 Physics question
A rigid body rotates about a fixed axis with variable angular velocity () at time t, where and are constants. The angle through which it rotates before it comes to rest is
Answer: (C)
Solution
The body comes to rest when , i.e. at . The angle turned is \int_0^{α/β}\dfrac{β t^2}{2}$|_{t=α/β} =
