Calculate the amount of energy consumed by a 75-kg person jumping up 70 cm for 10 minutes at a rate of one jump per second, assume a muscle efficiency of 20%. [Hint: 1kcal=D4184 ]

Step 1
First, we need to find the work done for each jump. Work = Force x Distance Force = Mass x Gravity (F = mg) Gravity (g) = 9.8 m/s² Mass (m) = 75 kg Force = 75 kg x 9.8 m/s² = 735 N Show more…

A $70 \mathrm{~kg}$ student consumes 2500 Cal each day and stays the same weight. One day, he eats 3500 Cal and, wanting to keep from gaining weight, decides to "work off" the excess by jumping up and down. With each jump, he accelerates to a speed of $3.3 \mathrm{~m} / \mathrm{s}$ before leaving the ground. How many jumps must he make? Assume that the efficiency of the body in using energy is $25 \%$
Power walking on level ground for 20 min consumes 175 kcal. For a $70.0-\mathrm{kg}$ person walking at $1.5 \mathrm{~m} / \mathrm{s},$ how much food energy would be consumed in $20 \mathrm{~min}$ walking up a $10^{\circ}$ incline? (Assume $20 \%$ conversion of food energy to mechanical energy.)
A person whose mass is $75 \mathrm{kg}$ is exposed to a dose of 25 rad. How many joules of energy are deposited in the person's bodv?
