Going up a hill would make your acceleration decrease or cause it to be slow. Going down a hill would make acceleration increase causing you to go faster.
you would be going north
The acceleration of the bike will depend on the general shape of the hill(ie. it's slope along the line of movement). If you don't take any friction into account, yes, the speed of the bike at the bottom will be greater if it goes from the bigger(ie. higher) hill.

First of all, your acceleration on the way down has no connection with what it wason the way up.Next, with the information given, there's no way to guess what your acceleration isin either direction.
When a roller coaster picks up speed going down a hill over time, this is known as acceleration. Acceleration can also include slowing down or changing direction in turns or loops.
Cycle down a hill.
coast
It doesn't. Going up it has the acceleration from the kick minus acceleration due to gravity. Going down it just has acceleration due to gravity. I suppose it could be the same if the former equaled 9.8 m/s
The force is the mass of the soil times the acceleration down the hill due to gravity.

a bike coming down hill has graventatinal energy.
