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
