The maximum energy a bone can absorb without breaking is surprisingly small. for a healthy human of mass 60 kg, experimental data show that the leg bones can absorb about 200 j. a. from what maximum height could a person jump and land rigidly upright on both feet without breaking his legs? assume that all the 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.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
