Question
Anne is working on a research project that involves the use of a centrifuge. Her samples must first experience an acceleration of 100g but then the acceleration must increase by a factor of eight. By how much will the rotation speed have to increase? Express answer as a fraction of the initial rotation rate.

For what value of Phi is 5 a maximum? What is the maximum s value? (You are required to maximize s with respect to pi for this part).Explanation / Answer
angular speed is given by
W=sqrt[a/r]
=>W1/W2=sqrt[a1/a2]
W1/W2=sqrt[100g/8*100g]
W2=2.83W1
so it has increase by 2.83 times
