Fleas have remarkable jumping ability. A 0.40 mg flea, jumping straight up, would reach a height of 35 cm if there were no air resistance. In reality, air resistance limits the height to 20 cm . A) What is the flea's kinetic energy as it leaves the ground? K = 1.37×10−3 mJ Part B At its highest point, what fraction of the initial kinetic energy has been converted to potential energy? Express your answer using two significant figures. f =...

DCI3.09. The Flyihg Leap of a Flea Part B High-speed motion pictures (3500 frames/second) of a jumping 200 ㎍flea yielded the data to plot the fleas acceleration as a function of time as shown in the figure (Figure 1) (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the measurements shown on...
