Question
A sledder has 800 J of potential energy and 200 J of kinetic energy at one point on a steep hill. How much kinetic energy will the sledder have at the bottom of the hill? (Assume negligible air resistance and friction.)
Answers
assuming that your potential energy is defined as zero at the bottom of the hill, all your energy is kinetic by the time you get there. 800 + 200 = 1000
Pert of this problem statement is missing though. In potentials, all you can define is differences. You have to define some point as zero.
