A heavy flywheel rotating counterclockwise about its middle at an original speed of 157.1 rad/s is slowing down because of friction in its bearings. a. If its acceleration is constant at 1.785 rad/s², find its angular velocity at the end of 1.00 minute. b. The flywheel is 5.50 m in diameter and has a mass of 985 kg. If the flywheel resembles a uniform disk, find the torque applied by friction.

Part a)

Final angular speed of the wheel is

Part b)

torque on the wheel is given as

Explanation:

Part a)

As we know that initial angular speed of the flywheel is

angular deceleration of the flywheel is given as

Final angular speed of the fly wheel is given as

Part b)

As we know that moment of inertia of the disc is given as

so we have

So torque on the wheel is given as

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

i think the answer is a and b

i wish you luck
