A roller coaster car starts with an initial speed of 0.375 m/s from the top of a section of a track that is sloping down at 26.2° to the horizontal. After traveling 80.3 m, it reaches the end of that section of the track and continues up the next section of the track that slopes up at 22.4° to the horizontal. If this section of the track has a length of 73.2 m, the car will not reach the top of the section.
