A centrifuge used in DNA extraction spins at a regular rate of 7000 rpm. Producing a "g force" on the sample that is 6000 times the force of gravity. If the centrifuge takes 10s to come to rest from the maximum spin rate a)what is the angular acceleration of the centrifuge b) what is the angular displacement of the centrifuge during this time?

Centripetal force = 13140 Newton.

Explanation:

Given the following data;

Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg

Velocity = 15m/s

Radius, r = 25m

To find the centripetal force, we would use the following formula:

Centripetal force = mv²/r

Substituting into the equation, we have;

Centripetal force = (1460*15²)/25

Centripetal force = (1460 * 225)/25

Centripetal force = 328500/25

Centripetal force = 13140 Newton.
