In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics.

In physics, rotational dynamics is the study of the kinematics and kinetics of rotational motion, the motion of rigid bodies, and the about axes of the body. It can be divided into the study of torque and the study of angular velocity.

Let's use that can America equation. We know the initial angular velocity is 30 radiance per second. We know the final angular velocity is negative. 30 radios for second, and we know the time is 10 seconds. And we desired thie angular displacement. And so we're going to state of mind. State or not, is equal to omega, not less omega over two times time. But you'll see whenever we plug, you know, maybe not. And omega, the right hand side, is equal to zero. So this is telling us that the angle displaced to zero, and that isn't either correct answer. And so I think that corresponds to a in a multiple choice. This makes intuitive sense because it spends half the time gaining positive angle and then the other Afghan in negative angle. And those two pieces are exactly symmetric, and so they exactly cancel out
