Awheel is rotating about an axis that is in the z direction the angular velocity ωz is 6.00 rad s at t 0 increases linearly with time and is 4.00 rad s at t 6.00 s we have taken counterclockwise rotation to be positive part apart completeis the angular acceleration during this time interval positive or negative positivenegativeprevious answerscorrectthe angular acceleration is positive since the angular velocity increases steadily from a negative value to a positive value part bpart completehow long is the time interval during which the speed of the wheel is increasing express your answer with the appropriate units t1 2.40 sprevious answerscorrectpart cpart completehow long is the time interval during which the speed of the wheel is decreasing express your answer with the appropriate units t2 3.60 sprevious answerscorrectpart dwhat is the angular displacement of the wheel from t 0 s to t 6.00 s θθ nothingradrequest answerprovide feedback
