Five ramps lead from the ground to the second
WebRamp C. Explanation: Let h be the height of the ramps. Sincethere is no friction, we can use the work- energy theorem. Wtot = Wperson + Wgravity = Δ K Hence for all the ramps, Wperson = - Wgravity + Δ K = mgh + Δ K In particular, if Δ K = 0 (the cart starts from rest and ends at rest), Wperson = mgh, for all the ramps. © © WebFive ramps lead from the ground to the second floor of a workshop, as sketched below. All five ramps have the same height; ramps B, C, D and E have the same length; ramp A islonger than the other four. You need to push a heavy cart up to the second floor and you may choose any one of the five ramps.
