WebNov 5, 2024 · The work done by those two forces is given by: W1 = − ΔU1 W2 = − ΔU2 where U1 and U2 are the changes in potential energy associated with forces →F1 and →F2, respectively. We can re-arrange the Work-Energy Theorem as follows 1: Wnet = WC + WNC = − ΔU1 − ΔU2 + WNC = ΔK ∴ WNC = ΔU1 + ΔU2 + ΔK That is, the work done by … WebAns: In this case, the work done on the cycle by the road will be equal to the work done by the stopping or the frictional force on the cycle due to the road. The angle between the stopping force and the displacement is 180 degrees. So, now the work done by the road is-. W = F d cosθ. W = 200 × 10 × cos180. fabrik19 gmbh
