### Question

I am trying to calculate the force required to move the target to hand. I setup the calculation so that the object will arrive at the hand when the target is at it’s highest position and that the object arrives always in the same time. There is no dampening.

```
var acceleration = Vector3.ZERO
var move : Vector3 = (hand.global_position - target.global_position)
var move_xz : Vector2 = get_flat_vector(move)
#target_time is half of the travel time
var time_pow = pow(2*target_time, 2)
#gravity_scale is 1.0 on all objects
var y_gravity = 1/2 * 9.81 * target.gravity_scale * time_pow
acceleration.y = ((move.y + y_gravity) * 2) / time_pow
acceleration = set_vector_xz(move_xz.normalized() * (4*move_xz.length()/time_pow), acceleration)
target.apply_central_force(acceleration * target.mass)
```
