First of all, there's no connection with your acceleration on the way up and on
the way down. Neither one has any effect on the other one.
Next, with the information given, there's no way to guess what your acceleration is
in either direction.
First negative, then posotive.
Only if the bike is coasting uphill.
A bike does not accelerate when turning a corner. A bike will slow down when going around a corner.
Yes, velocity and acceleration can point in the opposite direction to each other. This is because neither one depends on the other. When velocity and acceleration are opposite each other this results in slowing down, for example when you hit the break on your car.
You'll find a lot of people who call it "deceleration". But in real Physics, there's no such thing.There's only positive or negative acceleration, depending on whether the acceleration is inthe same or opposite direction compared to what you decided to call the positive direction.Negative acceleration is sometimes, but not always, associated with something that's slowing down.
Turning potential energy into kinetic energy. As you ride down the hill the potential energy you stored in your mass on the way up is converted into kinetic energy. That's why you speed up as you go down a hill and also why it's harder to go uphill.
Only if the bike is coasting uphill.
As my answer, it will be easier to walk uphill because force pulls your bike down and you might fall off and walking is easier.
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.
A bike does not accelerate when turning a corner. A bike will slow down when going around a corner.
In general, slowing down is negative acceleration. Some might call it deceleration. Braking a car or bike is a simple example of negative acceleration.

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.
Gravity
gravity!
The same as the relation between acceleration and any other force. Force = (mass) x (acceleration) If the force happens to be gravitational, then the acceleration is down, and the formula tells you the size of the acceleration. If the acceleration is down and there are no rocket engines strapped to the object, then it's a pretty safe bet that the force is gravitational, and the formula tells you the size of the force.
