[email protected] +1-574-658-4101 WebAs the pulley rotates through an angle θ, →F acts through a distance d such that d = Rθ. Solution Since the torque due to →F has magnitude τ = RF, we have W = τθ = (FR)θ = Fd. If the force on the string acts through a distance of 1.0 m, we have, from the work-energy theorem, WAB = KB − KA Fd = 1 2Iω2 − 0 (50.0N)(1.0m) = 1 2(2.5 × 10−3kg-m2)ω2. fairyland school lookout mountain https://theuniqueboutiqueuk.com
