Problem 7P

(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.]

Step-by-Step Solution:

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.
