A wheel is rotating about an axis that is in the z-direction. The angular velocity w is at -6.00 rad/s at t=0, increases linearly with time, and is at + 8.00 rad /s at t=7.0 sec. We have taken counterclockwise rotation to be positive. (a) Is the angular acceleration during this time interval positive or negative?(b) During what time interval is the speed of the wheel increasing? Decreasing? (c) What is the angular displacement of the wheel at t=7.0 sec.? *

Question

I need a complete solution here and answer must be in 4 decimal places. And also diagram.

A wheel is rotating about an axis that is in the z-direction. The angular velocity w is at -6.00 rad/s at t=0, increases linearly with time, and is at + 8.00O rad Is at t=7.0 sec. We have taken counterclockwise rotation to be positive. (a) Is the angular acceleration during this time interval positive or negative?(b) During what time interval is the speed of the wheel increasing? Decreasing? (c) What is the angular displacement of the wheel at t=7.0 sec.? *
