Problem 7P is a vector 14.3 units in magnitude and points at an angle of 34.8° above the negative x axis. (a) Sketch this vector. (b) Find Vx and Vy. (c) Use Vx and Vy 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.
