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.)?
The Attempt at a Solution
9.8(m/s^2)*12 kg = 117.6N
If the box was lifted straight up, the angle is zero.
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?
