The roller-coaster car shown below ( h1 = 41 m, h3 = 28 m, h4 = 11 m), is dragged up to point 1 where it is released from rest. Assuming no friction, calculate the speed at points 2, 3, and 4. State appropriate mks units with your answers. point 2 point 3 point 4 If 115,256 J of thermal energy was generated going from point 1 to point 3 , how fast would a 949 kg roller coaster be going at point 3 ? State the appropriate mks units with your answer.
