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.

In physics, a rigid body is an object that is not deformed by the stress of external forces. The term "rigid body" is used in the context of classical mechanics, where it refers to a body that has no degrees of freedom and is completely described by its position and the forces applied to it. A rigid body is a special case of a solid body, and is one type of spatial body. The term "rigid body" is also used in the context of continuum mechanics, where it refers to a solid body that is deformed by external forces, but does not change in volume. In continuum mechanics, a rigid body is a continuous body that has no internal degrees of freedom. The term "rigid body" is also used in the context of quantum mechanics, where it refers to a body that cannot be squeezed into a smaller volume without changing its shape.

have five angles here A B, C D. Yeah, and for each angle for a party, we have 45 degrees. Rather, Regan say 45.0 degrees. We have, ah, 60 0.0 degrees multiplied by 90.0 degrees, 360.0 degrees. And 445 degrees for converting from degrees to radiance. We have that to pirate raid. Ian's is equal to 360 degrees, and then we're going to use this conversion for every single part. You, too Pai Raid Ian's for every 360 degrees and and we're just repeating this. We should use our calculator, although for pie you could use 3.14 You can use your calculator in order to be, ah, a bit more accurate. And for part a there four per day. We are getting essentially pi over four radiance, or we can save 40.785 radiance for 60. This is pi over three, essentially or 1.5 radiance. Ah, for seed, we have pie over to radiance or 1.57 radiance, four part D. We have exactly two radiance, or we can say 6.283 radiance. And then for party. We have 89 pi over 36 or we can say 7.77 radiance. These would be your answers for all five parts. That is tthe e end of the solution. Thank you.
