$\cdot$ A wheel turns with a constant angular acceleration of 0.640 $\mathrm{rad} / \mathrm{s}^{2} .$ (a) How much time does it take to reach an angular velocity of $8.00 \mathrm{rad} / \mathrm{s},$ starting from rest? (b) Through how many revolutions does the wheel turn in this interval?

a) 12.5 $\mathrm{s}$b) 7.96 rev

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 quarter of this question, we have to kill plate the time taken by the wheel to attend the given. Well, you off the England exploration. What the time taken is denoted by t. We can conclude this time taken by using the definition off England expression which is now writing this Quinn 40. We have equals two. My God, Montezuma Guy wanted bail for college Equation one now setting the human values into this equation. One we will get equals two at 20.0 Radiant classic unmanageable, divided by 0.640 radian per second square. So this will you? Us equals two will 0.5 seconds. So let's come toward the second part of the question. In this part of the question we have to kill. Let the angler displacement, which is a traitor in order to kill Claire. This angle Let me ride the question. Hey, take will's door omega a D plus half off, 40 square quality question too, as my guy is equals tau zero. So the first part of this side will not contribute now setting the values into this equation too. We will get it takes balls to one by two into zero point 640 Ready in person Can square in tow one life seconds old square. So this will you us? Hey, take will store 50 born, gentle radiance revolutions. We can ID this will you as a medical store. 50.0, divided by two by revolutions. This will give us the table's too 7.96 delusions. So I know because you thank you.
