You push a file cabinet up a rough ramp tilted at 10.0° with horizontal at a constant speed of 1.50 m/s. The file cabinet has a mass of 30.0 kg and you are pushing with a 150 N force in the direction up along the ramp. It’s moved 4.20 m up along the ramp. Use g = 10.0 m/s2. Assuming the system is cabinet+earth+ramp, match the answers with questions. ΔK + ΔUg + ΔUsp + ΔEth + ΔEch = Wexternal
