1. The problem statement, all variables and given/known data

I have two known points A and B. I want to throw a ball from A to B with a certain angle. Obviously I also know the gravity.

For example: (in metres)

Known

point A: (0, 0, 0)

point B: (30, 0, 10)

direction: (0.949, 0, 0.316)

gravity: 9.82 m/s

angle: 45° or PI / 4

Wanted

acceleration: ?

How can I calculate the initial acceleration needed at point A for the ball to land on point B?

Thanks in advance.
