Question 4 (2 points) A roller coaster car breaks free at the ground level of a dip and is heading straight towards you at 12mls with 27 OOOJ of energy. What is the mass of the car that you are leaping away from? (5) A super-last engineer builds an escape track for this runaway car that leads up into the air at 56. How high up in the air should the end 0! this track be to stop the car? Remember to always support your answers. (5) Submit your numerical answer to two significant digits here and tull solutions to the drop box. Diagrams tor energy questions show the overall situation and what energies are significant at the required points of interest.
