It depends how fast the bat is moving.

Your missing some critical information. You need to know the speed of the bat at contact. Also would help to have the weights of the ball and the bat.
In the real world, outside of a physics class you would also need to know the plasticity of the ball and bat (how much energy of collision is passed into the ball and bat rather then just used in passed into the ball as acceleration).
Have fun.

Studies have been made involving this exact question and the speed leaving the bat is in the 120mph to 130mph range with a 100mph fastball and a 70mph swing. I will see if I can find the source for you. The reference below is not the one I was looking for but it will come close to answering your question. This is not a physics site and I am making the assumption you would just like to have some idea of the speed leaving the bat without all of the scientific data needed for an exact response.

That really depends on the ball.
I just finish editing part of a show in regards to baseballs and if I remember correctly...
If the bat does not move, it will bounce off at about 1.5 to 1.7 its original speed according to its testing and own acceptable benchmarks.
However, as I said, that depends on he manufacturer of the ball, the materials it uses.

Is it an inelastic or elastic collision? What is the speed of the bat? Cant answer the question without that data. Normal baseball weight? What is the weight of the bat?

I think it requires more known factors than you have listed.
Bat speed and where on the bat it was hit would have a factor in determining the speed of the ball as well.

Depends on the bat speed and what material the bat is made of.

It depends on how hard the batter can swing the bat.

I just saw this on Myth Busters. Its between 65 and 75.

120MPH is near the maximum -
