Use the following information to answer the next three questions A roller coaster with mass 1.77x103 kg follows the section of track drawn below. At point A, it travels at a speed of 10.7 m/s. Nureric Response 10. The total mechanical energy of the roller coaster at point A, using the measurements in the image, is a bc 100 J. The values of a, b, cand d are and (Record your answer in the numerical-response section below.) Your answer DODO 13. As the roller coaster descends from point A to point B, it loses 434 kJ of potential energy. Which of the rows below correctly gives the change in kinetic energy (KE) and mechanical energy (MB) for the roller coaster in that time? (assume there is no friction) Row Change in KE Change in ME -434 kJ +434 kJ -434 kJ +434 kJ +434 kJ +434 kJ
Nuretic Response 11. Assuming that there is no friction or air resistance, the speed of the roller coaster at point C will be m/s. (Record your answer in the numerical-response section below.) Your answer: 0000
