Aroller 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.

The first thing you should mind in order to solve it is to  neglect friction, then just find the height at the first part and of the second part (which is less than the the first one). Everything is sorted out, so :



Now you can clearly see that in the first section there is a great PE, which is greater than in the second part so we can conclude that it will excess KE in second section  anyway.
Hope that helps!
