Friction acts on a rotating disk, causing its angular speed to change with time as given by: $\frac{d\theta}{dt} = \omega_0 e^{-\sigma t}$ where $\omega_0$ and $\sigma$ are constants. At $t = 0$, the disk's angular speed is 3.30 rad/s. At $t = 10.8$ s, the angular speed is 2.00 rad/s. (a) What are the values of the constants $\omega_0$ (in rad/s) and $\sigma$ (in s?¹)? $\omega_0 = $ ____ rad/s $\sigma = $ ____ s?¹ (b) What is the magnitude of the angular acceleration (in rad/s²) at $t = 3.00$ s? ____ rad/s² (c) How many revolutions does the disk make in the first 2.50 s? ____ revolutions (d) How many revolutions does it make before coming to rest? ____ revolutions
