The turntable in a microwave oven has a moment of inertia of 0.039 kg⋅m2 and is rotating once every 4.4 s . Part A What is its k
gayaneshka [121]

To solve this problem it is necessary to apply the concepts related to Kinetic Energy, specifically, since it is a body with angular movement, the kinetic rotational energy. Recall that kinetic energy is defined as the work necessary to accelerate a body of a given mass from rest to the indicated speed.

Mathematically it can be expressed as,

KE = \frac{1}{2} I\omega^2

Where

I = Moment of Inertia

\omega =Angular velocity

Our values are given as

I = 0.039kg\cdot m^2

A revolution is made every 4.4 seconds.

\theta = 1 rev \rightarrow 4.4s

\Rightarrow \omega = \frac{1rev}{4.4s}

If the angular velocity is equivalent to the displacement over the time it takes to perform it then

\omega = 0.2272rev/s(\frac{2\pi rad}{1rev})

\omega = 1.42rad/s

Replacing at our previous equation we have,

KE = \frac{1}{2} I\omega^2

KE = \frac{1}{2} (0.039)(1.42)^2

KE = 0.03993J

Therefore the kinetic energy is equal to 3.9*10^{-2}J
