what's answer of number 8????

\"1* INELASTIC COLLISION RESULTS 5. Show (derive) that the theoretical percentage loss of total kinetic energy in terms of the cart masses is given by: Q m2 = 100 KEi m1 +m2 A] where Q represents the energy lost after the collision. Show all steps of your derivation. (Hint: Start with conservation of momentum and energy for the general case of a totafg'y inefam': roifirim. Solve the conservation of momentum expression for the velocity after the collision remembering the carts stick together. Then substitute the expression for the velocity after the collision into the conservation of energy equation. Do not forget to include an energy term \"Q\" to represent any energy lost in the collision.) 6.

Calculate the experimental d and :values for the mean Ap of the inelastic collision trials. Do these values indicate your results agree or disagree with conservation of momentum as it applies to inelastic collisions? 8. Observe the values you calculated for experimental and theoretical energy losses in an inelastic collision. Discuss if the results agree or disagree with momentum conservation as it applies to inelastic collisions? 9. Look at your results for the energy loss in inelastic collisions. Compare the actual measured energy loss to the derived theoretical energy loss. Does the theoretical energy loss do a decent job of predicting actual energy loss in the collisions? Answer: Theoretical data serves as a valuable reference for acquiring actual or experimental data. In most cases, the observed energy loss is either equal to or higher than the theoretically predicted energy loss. Upon reviewing the data table, it becomes evident that the actual energy loss significantly exceeds the theoretical predictions. The theoretical data provides a foundational understanding that helps guide the interpretation and analysis of experimental results. 10. Given the design and setup of our experiment, discuss if you would ever expect the system of two carts to gait: energy after the collision. Discuss what it would mean if you did observe an increase in energy after the collision. 11. Across all collisions (elastic and inelastic) momentum should be conserved. What does it mean if momentum is not conserved, or rather what general physics concept is affecting the system if momentum is not conserved. Given our experiment, what could cause momentum to not be conserved? Hint: Think about critical aspects of the setup or design of the equipment that if done incorrectly would affect the outcome
