- pls help not in scientific notation pls⦁ Envision yourself doing a jumping jack. Imagine you assume a standing X position, with your arms above your shoulders in a wide V and legs apart in an inverted V. When you hold that position, you are demonstrating ______ energy. When you do the jumping jack from the previous position you are converting that energy into _____ energy. ,Determine the energy lost, due to friction, as an 8000 N car that skids to a stop, if its initial velocity was 12 m/s.
- #13 Work Energy TheoremA mass M with an initial velocity v0 slides across a level surface, subject to a force of friction where the coefficient of kinetic friction is μk, eventually coming to a halt. The total work done on the mass A. depends on μk B. depends on both μk and the initial speed v0 C. depends on neither μk nor the initial speed v0 D. does not depend on μk, and is given by 1/2MvAnswer 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?
