An arrow in a bow has 70 j of potential energy. assuming no energy loss, how much kinetic energy will it have after it has been shot? 140 j 70 j 50 j 35 j

There is no solution required for this problem. You just have to analyze and understand the Conservation Law of Energy. Energy can't be made or destroyed, it's only transformed from one form to another. So, if the potential energy is transformed to kinetic energy, the value of that energy would still be 70 J.
