Part a) "Conservation of energy" In order to study the conservation of energy, we will need first to write down the mass of the given skater: Build a track with an initial height of 8 meters, place the second "red dot" on the ground and the last one at a height of 4 meters. ( Do not worry if the skater leaves the track after the simulation), make sure you pause so you can measure all the energies needed. M = Then, we will build a table of the form: Initial height (m) KE() PEND KEF(D PERO 8.0 And a second table: Mechanical Energy initial (!) Viechanical Energy final (!) % error
