1. The problem statement, all variables and given/known data Estimate (to the nearest order of magnitude) how much work I must do to pick up a 12 kg box to a height of 1.3m. Does it mattert how I pick up the box (fast or slow, straight up or along a curvy path, etc.)? 2. Relevant equations W=Fcos(x)S 3. The attempt at a solution 9.8(m/s^2)*12 kg = 117.6N W=Fs W=Fcos(angle)s s=1.3m If the box was lifted straight up, the angle is zero. W=117.6cos(90)(1.3m) W=0 It does not matter if you pick the box up slow or fast. I'm confused at the curvy part of the question. If I pick up the box at an angle, is it always negative since I'm doing work against gravity?
