Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

The graph in the figure shows the position of an object as a function of time. The letters H-L represent particular moments of time.

The graph is a curve that starts at a point on the time axis at H, rises to a peak at I, and then descends past point J to a lower position at K, before leveling out and decreasing slightly at L.

**Question:**
At which moments shown (H, I, etc.) is the speed of the object

(a) the greatest?
(b) the smallest?

**Multiple Choice Options:**
- (a) J, (b) L
- (a) I, (b) L
- none of these
- (a) J, (b) I
- (a) I, (b) K
- (a) H, (b) L

Q1. The image below shows an example of "absolute dependent motion analysis", where the motions of two objects depend on each other, and the goal is to find the relations in their motions (i.e., in their positions, velocities, and accelerations). Please put the suggested steps of analysis in the correct order. VA A B VB Differentiate the entire equation with respect to time, and extract the relation in velocities. Repeat for acceleration if needed. Set up a coordinate (s) along the direction of motion from a fixed point (O) or a fixed datum line. Represent the positions of the objects respectively. In some cases intermediate objects need to be considered too and their positions need to be represented as well. Recognize the constant length(s) and find the depending geometric relations between the position variables.
1. For this series of 3 questions, a jet bike is moving along a straight road with the speed described by the v-s function v(s) = 2. s2/3, (v in [m/s] and sin [m]). Your final goal is to determine the velocity (v) at a specified time. But before that, you need to answer some other questions. 3) determine the velocity (v) when the time t = 7.1 s. Your answer must include 2 places after the decimal point, and the proper unit. Your Answer: Answer units
(1-C.s) m/s² where Cis a constant and sis Q13. The acceleration of a particle traveling along a straight line is a the position in m. If the constant Cis 0.1, the initial velocity vo is 0, and the initial position so = 1.7 m at time t = 0, determine the particle's velocity v when its position s = 4.8 m. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. Answer: =
