Answer:
The displacement in t = 0,
y (0) = - 0.18 m
Explanation:
Given f = 40 Hz , A = 0.25m , μ = 0.02 kg / m, T = 20.48 N
v = √ T / μ
v = √20.48 N / 0.02 kg /m = 32 m/s
λ = v / f
λ = 32 m/s / 40 Hz = 0.8
K = 2 π / λ
K = 2π / 0.8 = 7.854
φ = X * 360 / λ
φ = 0.5 * 360 / 0.8 = 225 °
Using the model of y' displacement
y (t) = A* sin ( w * t - φ )
When t = 0
y (0) = 0.25 m *sin ( w*(0) - 225 )
y (0) = 0.25 * -0.707
y (0) = - 0.18 m

Below is an attachment containing the solution.
understandable terms created for the physichs terms can create mass destruction in the fires created with force
A stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
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
