A centrifuge rotor has a moment of inertia of 3.30 10-2 kg·m2. How much energy is required to bring it from rest to 10000 rpm? I used KE=1/2Iw^2, but that answer i'm getting is incorrect. what am i missing?

This question didn't post properly. I was able to find the acceleration (1.79m/s^2), having difficulties getting the force. what would "h" be in your equation? to me that symbolizes height and there's no height in this problem.

Two crates, of mass m1 = 60 kg and m2 = 130 kg, are in contact and at rest on a horizontal surface (Fig. 4-54). A 620 N force is exerted on the 60 kg crate. The coefficient of kinetic friction is 0.15 a)Calculate the acceleration of the system. b) calculate the force that each...

**algebra**

That's odd, you can't solve this problem if it is not set to equal something. The only thing i can think of is to set it equal to 0 ans solve for j.

what is this supposed to be equal to? You cannot combine -108 and -9j since they are not like terms (they don't both have j).

**Algebra**

What is true of a square root? You cannot take the square root of a negative number (if you're dealing with real numbers anyway). So for what value of X would 12x-24 be 0? anything below that number would make 12x-24 negative and therefore not in the domain.
