FIGURE 7.14 For Thought and Discussion 1; Problem 30
Expert Solution & Answer
To determine
To determine and explain: which is conservative and non-conservative forces with given figures.
Answer to Problem 1FTD
Figure (a) follows the conservative force system.
Figure (b) follows the non-conservative force system.
Explanation of Solution
Refer to the Figure 7.14 (a) in the question.
The magnitude of force in the force vectors at different points in space is equal. This statement gives information that it’s present in closed path.
Therefore, the given force of vectors follows the conservative force system.
Refer to the Figure 7.14 (b) in the question.
The magnitude of force vectors at different points in space is unequal and the magnitude of magnitude of force varying from place to place and point to point. Due to some external force these changes may occur. The non-conservative force definition states that due to some frictional force the force will act opposite to the motion.
Therefore, the given force of vectors follows the non-conservative force system.

Consider the woman doing push-ups in the figure. She has a mass of 49.2 kg, and the distance from her feet to her center of mass is 0.96 m, while the distance from her feet to her hands is 1.75m.
a. How much work in joules does she do if her center of mass rises 0.27 m?
b. What is her useful power output, in watts, if she does 25 pushups in one minute? For the sake of simplicity, ignore any power used by her muscles lowering her body during each pushup.
You reach out of a window 15 m above the ground and toss a ball straight up with a speed of 10 m/s. Neglecting air resistance, what is (a) the ball’s maximum height above the ground, and (b) the ball’s speed when it hits the ground?
