- 3. DETAILS n mq MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.95 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on…Quantitative Analysis - Introducing Elasti For each of the following situations: a. Choose an initial and final state (states A and B) that will be appropriate (interesting) for analysis. b. If there is not already a physical diagram of the situation and there should be one for proper analysis, include one. c. Construct a system schema of the situation. Do not forget to include the system boundary for the system specified by the problem. Choose your system wisely. d. Construct an energy bar chart and system flow diagram (LOL plots) for each problem. e. You are allowed to add other energy storage modes. You do not have to use the energy storage modes that are printed in each LOL plot. f. Find the unknown value. 1. A toy car is pressed onto a small spring so that it compresses it 5 cm and is then released. The spring's stiffness constant is 400 N/m and the cart's mass is 250 g. How fast is the cart moving when it leaves the spring?I'm trying to understand the different types of energies. I understand the definitions, but when I apply them to situations, it doesn't make much sense to me. I have the following: A. Entrophy - measure of the amt of disorder, or randomness in a system B. Kinetic Energy - Energy in Motion C. Heat - kinetic energy contained in the random motion of atoms & molecules D. Chemical Energy - type of potential energy which arises from the arrangement of atoms and be release in chemical reactions E. Conservation of Energy: Kinetic to Potential Energy - its not possible to destroy or create energy F. Conservation of Energy: Potential to Kinetic G. Potential Energy - Energy an object has because of its location or structure When I try to apply to the following, I come up with this: A: A Glass falls off the shelf & breaks B. An orange falling from a tree C. During exercise you get extremely hot. D Animals consume food (organic molecules) to make ATP to walk, breathe, etc. E. A large…
