(II) is a vector units in magnitude and points at an angle of above the negative axis. (a) Sketch this vector. (b) Find and Use and to obtain (again) the magnitude and direction of . [Note: Part (c) is a good way to check if you've resolved your vector correctly.]
Solution 7P Introduction Given in the question that 25% of chemical energy is converted to mechanical energy. Therefore, remaining (100-25)% = 75% will be mechanical energy as Total energy= Chemical energy+mechanical energy. Step 1: Total metabolic power is =480 W Now, 75% of total metabolic power is converted to thermal energy.
