A fun-loving 11.4 kg otter slides up a hill and then back down to the same place.
she starts up at 5.75m/s and returns at 3.75m/s , how much mechanical energy did she lose on the hill?

The toal mechanical energy = gravitational potential energy + kinetic energy.
the potential energy is the same before ...
It calculates the mechanical energy that the otter lost on the hill when sliding up an back down.
