If the wheel started with half of its initial angular velocity, but had the same angular acceleration, how would the graph change?
the slope would change from 3 rad/s/s to 1.5 rad/s/s
the area under the curve for the first 3 s would change from 13.5 rad to 27 rad
the y-intercept of the graph would change from -9 rad/s to -4.5 rad/s
the slope would change from 3 rad/s/s to 6 rad/s/s
