Agrinding wheel with a mass of 10.50 kg and a radius of 0.55 m is initially at rest. what angular momentum will the wheel have 9.50 s after a 7.50 nâ·m torque is applied to it.

Explanation:

As we know by Newton's law of rotational motion that Rate of change in angular momentum is total torque on the system

So here we have

here we can say it

so final angular momentum of the disc is given by the equation

now we know that

time interval is given as

since it is initially at rest so initial angular momentum is ZERO

so we have

answer: i don't know the answer good luck
