Just fill in the bolded stuff with whatever you want and please draw a diagram
At t=0, a disc has an initial angular velocity ωi= (+/-) X radians/second and makes an initial angle thetainitial=X radians. a) if it has an angular velocity of X1 radians/second up till time t1 and a subsequent angular velocity of X2 rad/sec up till time t2, what is it's final angular displacement? (as we did before, you can 'integrate' the graph of angular-velocity vs. time to solve this) b) If, instead, it simply has a constant angular acceleration of X rad/s2 over the period 0<t<t2, what is both it's final angular velocity as well as its total angular displacement, assuming an initial angular velocity of X1 radians/second?
Homework Answers
To calculate the change in the angular displacement we generally
do integration of the graph between angular velocity and time, or
we can also take the area of the plot between them. I have done by
both the methods. I hope that helps. Thank you.
