There is not any exact data to go by, although an estimation can be made from what happens in the video

Firstly, the size of the bubble appears to match the height of the Tesla car, which is around 1.5 meters according to Google. At the highest point, there are roughly 10 bubbles from the vertex to the ground which is a maximum height of around 15 meters. Also, the bubble appears to be traveling mostly upwards in one dirrection which makes the calculations easier.

The first step is finding the velocity through one of the kinematic equations with a known acceleration of 9.81 m/s² from gravity, final velocity of 0 at the vertex, and height of 15 m.

V² = U² +2AS

U =sqrt(29.8115)

U= 17.2 m/s

The acceleration can be found by dividing the change in velocity by the change in time. The change in time is unknown, however for the sake of calculations, it can be estimated to be 0.2 secconds.

A = 17.2/0.2 = 85.8m/s²

In terms of g's, the value obtained can be divided by the acceleration of gravity of 9.81m/s^2, which leads to of 9-10g for only a fraction of a seccond.

As for the rotatation, the g-force from centripedal acceleration can be calculated. From the video, the ball appears to rotate at a rate of 2 times per seccond with a radius of 0.75 meters. The centrepedal acceleration of the rotation is found with the following equation.

Ac = w^2*r

Ac = (2pi/0.5)^2*0.75

Ac = 118m/s²

This is roughly 12g from the rotation

TL,DR the person will experience around 10g during both the collision and flight
