- Homework Statement
- A sphere is initially rotating with angular velocity w_0 in a viscous liquid. Friction causes an angular deceleration that is proportional to the instantaneous angular velocity,α=-Aw, where A is a constant. Show that the angular velocity as a function of time is given by

w=w_0 exp(At)

- Relevant Equations
- w=w_0 +∫α dt

I am not understanding how to even start the question
