You need to design an industrial turntable that is 60.0 cm in diameter and has a kinetic energy of 0.250 J when turning at 45.0 rpm v (a) What must be the moment of inertia of the turntable about the rotation axis? (b) If your workshop makes this turntable in the shape of a uniform solid disk, what must be its mass?

a) 0.023 $\mathrm{kg} \mathrm{m}^{2}$b) 0.51 $\mathrm{kg}$

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.

In the first part of this question, we have to get laid the moment off in Russia, off a turntable, Let the moment of inertia eyes. I defined the traditional kinetic energy care rotational equals to one by two. I will make that square sold in this quaint for I. We will get Michael's toe to carry additional you wanted by my Gods Square. So call it quite in one. Now sitting the values into this equation, we will get Michael's toe two months. Clever zero point 250 You old he wanted by 45 points. You don't want to fly away to buy Brilliant wanted by 60 whole square. So this would give us I equals two little point 2 to 5 crazy meter square. So this is the answer The first part of this question. Now let's come for the second part off this question. This part off the question we have to kill. Let the mess off this turntable if he tells the shape of our solar disk in order to kill Colette, the Mass we need to write the formal off our moment off inertia, which is Michael's too. One by two m. R. square Now, writing the square for him, we will get, um, equals to do. I wanted by our square. So call it equating to sitting the values into this question. We will get, um, equals to two months. Played by 0.0 to 25 kg meter square, divided by 0.300 meter hold square. So this will give us chemicals to 0.500 Katie. So end of the question. Thank you.
