The platter of the hard drive of a computer rotates at 7100 rpm = revolutions per minute = rev/min).
Part A. Find the angular velocity of the platter?
Part B. If the reading head of the drive is placed 3 centimeter from the rotation axis, find the linear speed of the point on platter just below it?
Part C. If a single bit requires 0.50 meter of length along the direction of motion, find how many bits per second can the writing head write when it is 3 centimeter from the axis?
