- Explain how you know there is work being done on an object?The unit of work, joule, is dimensionally the same as: a. Newton‑meter b. Newton/kilogram. c. kg•m2/s2 d. a and c e. a and b f. b and cAnswer both or NONE question 1 - For exercise, an athlete lifts a barbell that weighs 400 N from the ground to a height of 2.20 m at a constant speed in a time of 1.60 s. What is the metabolic power, in kW (kiloWatts)? Your answer needs to have 2 significant figure, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Question 2 - The metabolic power for typing is 150 W for Lili, not a lot as you know probably. How long does it take to burn off the energy in a slice of apple pie, which energy content is 1680 kJ (400 food calorie), in minutes? (Try to stay active, working/studying in front of a computer is not the best exercise you can do for your body.)
