A wheel is turning about an axis through its center with constant angular acceleration. Starting from rest, at t=0t=0, the wheel turns through 8.75 revolutions in t=t= 13.0 ss . At 13.0 ss the kinetic energy of the wheel is 36.0 J Part A For an axis through its center, what is the moment of inertia of the wheel? Express your answer with the appropriate units.

The moment of inertia is 1.01 kg m²

Explanation:

Given:

θ = 8.75 revolutions = 2π * 8.75 = 54.98 rad

t = time = 13 s

Ek = kinetic energy = 36 J

The angular acceleration is equal to:

The angular velocity is:

w = αt = 0.65 * 13 = 8.45 rad/s

The moment of inertia is:

1/0.14nm = 10^10/1.4 a lot

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
