This worksheet cannot be solved as presented.
The instructions require completing questions based on computer simulations, which are not provided. Simulation #1 asks to determine an unknown height using change in momentum and kinetic energy lost, but no numerical data (mass, velocities, heights, or energy values) from the simulation is given. Similarly, Simulation #2 on inelastic collision provides no masses, initial/final velocities, or other parameters needed for calculation.
Without the specific data generated by the simulations, it is impossible to perform the required calculations or provide any numerical answers. The worksheet is incomplete for solving without access to the referenced simulations.
