A 65.0 {\rm kg} person is put on an exercise program by a physicaltherapist, the goal being to burn up 510 food calories in eachdaily session. Recall that human muscles are about21.0 \% in converting the energy they use up into mechanicalenergy. The exercise program consists of a set of consecutive highjumps, each one 50.0 {\rm cm} into the air (which is pretty good for a human) andlasting 1.50 {\rm s}, on the average.
How many jumps should the person do persession?
