How to calculate number 7?. whats answer of number 7

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 = 1000 KE; m1 +m2 /" 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 totaf; 733.7432? (Miriam 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 tvalues 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? 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? 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? Given the design and setup of our experiment, discuss if you would ever expect the system of two carts to gain energy after the collision. Discuss what it would mean if you did observe an increase in energy after the collision. Across all collisions (elastic and inelastic) momentum should be conserved. What does it mean if momentum is n01 conserved, or rather what general physics concept is affecting the system if momentum is ma: conserved. Given our experiment, what could cause momentum to mt be conserved? Hint: Think about critical aspects of the setup or design of the equipment that if done incorrectly would affect the outcome
