A spinning disk is rotating at a rate of 2 rad/s in the positive counterclock-wise direction. If the disk is slowing down at a rate of 4 rad/s 2 , Find the wheel's angular velocity in rad/s after 4 s. o ω = ω o + αt. o ω= 2 + (-4*4)  negative because slowing down o ω= -14 A spinning disk is rotating at a rate of 4 rad/s in the counterclockwise direction as shown in the figure.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
