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 center axle

The speed will be "3.4×10⁴ m/s²".

Explanation:

The given values are:

Angular speed,

w = 7200 rpm

i.e.,

  =

  =

Speed from the center,

r = 6.0 cm

As we know,

⇒  Linear speed,

On putting the estimated values, we get

Now,

Acceleration on disk will be:

⇒  

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

it has to be b, about 97 percent.
