76. The wheel starts turning from rest (ω0= 0) at t= 0, and accelerates uniformly at 22.00 rad/sα=.Betweent1and t2the wheel turns through Δθ= 90.0 rad, where t2– t1= Δt= 3.00 s. We solve (b) first. (b) We use Eq. 10-13 (with a slight change in notation) to describe the motion for t1≤t≤t2:ΔΔΔΔΔΔθω=+¡=−121122tttt()which we plug into Eq. 10-12, set up to describe the motion during 0
