Assignment:
Question 1. Your new exercise machine involves lifting weights a standard height of 52.0 cm.
a) How much work do you do if you lift 37.8 kg? (in J)
Exercise requires a food input about four times your mechanical work output (in other words, about 25% efficiency). A "food calorie" is actually 1000 standard calories and a standard calorie is 4.185 J. Each pound of fat represents 3,500 "food calories".
b) How many time must you lift the weight to lose one pound of fat.
