Homework Statement
The graph shows the behavior of an object with the moment of inertia of 18 kgm^2
a) Calculate the magnitude of the constant torque that acted on the system.
b) Through what angle did the object rotate between t=2 and t=20 seconds?
Homework Equations
http://homework.sdmesa.edu/cmona/195/PS/195THQ08S12.pdf
Torque = (Moment of Inertia)(Angular Acceleration)
tangential speed = (radius)(angular speed)
theta(final) = theta(initial) + (initial angular speed)(time) + (.5)(angular acceleration)(time^2)
The Attempt at a Solution
Since I'm given the moment of inertia, all I need to do is determine the angular acceleration of the object and substitute it into the equation for torque, along with the value for moment of inertia. I'm given a graph of the log of angular displacement vs. log time (the link I've provided...question 2). I'm not sure how to use this to determine the value(s) I'm looking for. Thanks in advance
