Tutorial: Using energy bar charts for conservation of energy problems C. A box (m = 2 kg) is moving upward at v = 5 m/s. A student is Initial and final situation + forces pulling the box up via a rope using a force of F = 30 N and kspace applies the force for a distance of d = 5 m. How fast is the box moving after it has traveled 5 m? KE Ug, Us, Wother AEth KEr Ugr Usr enter I shift D. You are pushing a box (m = 4 kg) starting from rest horizontally with a constant force F = 30 N. After pushing it for a distance d = 5 m, the box reaches a hill inclined at 0 - 250. You stop pushing the box as soon as it reaches the hill. The coefficient of kinetic friction between the box and the road is uk = 0.4 and the hill is frictionless. How far up the hill is the box going to go? Initial and final situation + forces KEi Ugi Usi Wother Eth KEr Ugr Use
