The turntable of a record player has an angular velocity of 8.0 rad/s when it is turned off. the turntable comes to rest 2.5 s after being turned off. through how many radians does the turntable rotate after being turned off? assume constant angular acceleration

Distance covered will be 10 radian

Explanation:

We have given initial angular velocity

As the record player finally stops so final angular velocity

Time t = 2.5 sec

From first equation of motion we know that

So

Now we know that

So distance covered will be 10 radian

less than one you can't create energy
