As a result of friction, the angular speed of a wheel changes with time according to dθ/dt = ω0e^−σt where ω0 and σ are constants. The angular speed changes from 3.70 rad/s at t = 0 to 2.00 rad/s at t = 8.60 s. a. Use this information to determine σ and ω0.
σ = s−1
ωo = rad/s

b. Determine the magnitude of the angular acceleration at t = 3.00 s.
rad/s2
c. Determine the number of revolutions the wheel makes in the first 2.50 s
rev

d. Determine the number of revolutions it makes before coming to rest.
rev
