Calculate the acceleration of the train during the trip down the first hill
Time for train to go from top of hill to bottom:3.5 s
Time for train to pass point at top of hill 1.5s
Time for train to go from bottom to top of first hill:7 s
Time for train to pass point of bottom of hill:1s
Height of hill: 16.155 m
The Attempt at a Solution
I tried using that equation but there is two variables missing distance and acceleration. I can't use the height of the hill because isn't this a x problem (parallel problem)? I don't understand how I can find the acceleration of the rollercoaster train during the trip down the hill with only this data.
