The maximum energy a bone can absorb without breaking is surprisingly small. For a healthy human of mass 60kg, experimental data show that the leg bones can absorb about 200J (a) From what maximum height could a person jump and land rigidly upright on both feet without breaking his legs? Assume that all energy is absorbed in the leg bones in a rigid landing.(b) People jump from much greater heights than this; explain how this is possible.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
