An object whose moment of inertia is 4.10 kg/m^2 experiences the torque shown in the graph attached.

What is the object's angular velocity at 2.70 s? Assume it starts from rest.

My main problem i think is how to read the graph. How should i interpret the graph?

What i would do first is find the angular acceleration by using...

aa = angular acceleration

t = torque

I = moment of inertia

aa= t/I

I would find the aa for three parts, the part where it is accelerating positively, when it is not increasing, and then when it decreases.

I would then use the aa for the equation while putting in the velocity...

w = angular velocity

T = time

w(f) = w(i) + aaT
