Objects tend to come to rest at a position of lowest potential
energy. Think of a machine or system that works against this
tendency. Describe how kinetic energy is needed to increase
the system's potential energy.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .

Which of these is the best way to manage a natural resource
