76. The wheel starts turning from rest ( ω 0 = 0) at t = 0, and accelerates uniformly at 2 2.00 rad/s α = .Between t 1 and t 2 the wheel turns through Δ θ = 90.0 rad, where t 2 t 1 = Δ t = 3.00 s. We solve (b) first. (b) We use Eq. 10-13 (with a slight change in notation) to describe the motion for t 1 t t 2 : ΔΔ Δ Δ Δ Δ θω =+ ¡ =− 1 2 1 1 22 tt t t () which we plug into Eq. 10-12, set up to describe the motion during 0
