A certain CD has a playing time of 74.0 minutes. When the music starts, the CD is rotating at an angular speed of 480 revolution
Rashid [163]

Answer: 0.00636\ rad/s^2

Explanation:

Given

CD has a playing time of t=74\ min\ or\  74\times 60\ s

Initial angular speed of CD is 480\ rpm

Final angular speed of DC is 210\ rpm

Angular speed, when rpm is given

\omega =\dfrac{2\pi N}{60}

\omega_i=\dfrac{2\pi \times 480}{60}\\\\\Rightarrow \omega_i=16\pi \ rad/s

Final speed

\Rightarrow \omega_f=\dfrac{2\pi \times 210}{60}\\\\\Rightarrow \omega_f=7\pi \ rad/s

Using equation of angular motion

\Rightarrow \omega_f=\omega_i+\alpha t

Insert the values

\Rightarrow 7\pi =16\pi +\alpha \times 74\times 60\\\Rightarrow -9\pi =\alpha \cdot (4440)\\\\\Rightarrow \alpha=-\dfrac{9\pi}{4440}\\\\\Rightarrow \alpha=-0.00636\ rad/s^2

Magnitude of angular acceleration is 0.00636\ rad/s^2

When a pendulum is at the center position, what is true of the kinetic and potential energy?
guajiro [1.7K]

Answer:

Kinetic energy

Explanation:

When a pendulum is swinging about its mean position, the total energy is conserved.

At the mean position, the kinetic energy is maximum but the potential energy is zero.

At the extreme position, the potential energy is maximum but the kinetic energy is zero.
