Answer:
Normal force will be equal to 8.945 N
Explanation:
We have given mass of the cylinder m = 8.15 kg
Diameter d = 15 cm
So radius
Initial angular velocity
As the cylinder finally comes to rest so final angular velocity
Before coming to rest cylinder covers a distance of
From third equation of motion
Coefficient of kinetic friction
Moment of inertia of the solid cylinder
We know that
So normal force will be equal to
