A hard drive disk rotates at 7200 rpm. The disk has a diameter of 5.1 in (13 cm). What is the speed of a point 6.0 cm from the c
ExtremeBDS [4]

Answer:

The speed will be "3.4×10⁴ m/s²".

Explanation:

The given values are:

Angular speed,

w = 7200 rpm

i.e.,

  = 7200 \times  \frac{2 \pi}{60}

  = 753.6 \ rad/s

Speed from the center,

r = 6.0 cm

As we know,

⇒  Linear speed, v=wr

On putting the estimated values, we get

                               =753.6\times 0.06

                               =45.216 \ m

Now,

Acceleration on disk will be:

⇒  a=\frac{v^2}{r}

       =34074 \ m/s^2

       =3.4\times 10^4 \ m/s^2
