Trajectory Prediction in Unity -- 2

I need a trajectory prediction script that can predict where an object will land after shooting it and when it bounces. For example, If an object is launched at Vector3(0,0,0) and the destination is set to Vector3(10, 15, 6), at a given angle x, how much force will it require to get there, and if it lands and bounces, the script should also be able to predict where it'll land again. Please check: [login to view URL] I want it to work like that and but with the launch and distance calculation function For example; CalculateRequiredVelocityTo(Vector3 targetPosition) // Calculates the velocity or force required to be applied object to move it to the target position Launch(Vector3 targetPosition) // Performs the launching of the object The motion and calculations also have to take air resistance (drag) and object's mass into consideration. The should be options to acceleration and deceleration.
