Using the following accelerometer data of the Helix rollercoaster ride, I need to make proportional free body diagrams (Normal force and mg force) of someone with a fixed mass of 80kg on the ride. If possible, any working out to find the velocity or radius would be appreciated :)

Also, it needs to be for three points: one where there are positive g force, negative g force and 0 g force. If not, literally anything helps :)

There are links to a POV video and drone video of this ride.

Helix - 2014 . Projekthelix.se with blog, photos, movies and much more. launch video Mack Rides Track length: 1 355 m . Top speed: 100 km/h . Elevation difference: 41 m G-force: 4.3 G . Ride time: 130 sekunder . Capacity: Around 1350 riders/hour . 2 LSM launches . Train mass: 8730 kg (empty) . Train length: 12.5 m Helix is be a roller coaster with many exciting elements, as you may guess from the video. The ride starts in a high position, at the foot of the AtmosFear tower. During the first part of the ride, the train uses the initial gravitational energy, before reaching the first launch. The launch uses electromagnetism: LSM - Linear Synchronous Motors - in contrast to the hydraulic launch of the Kanonen roller coaster. This technology may inspire a new interpretation of Einstein's first paper on relativity "Zur Elektrodynamik Bewegter Korper" 'On the Electrodynamics of moving bodies". A variable magnetic field in the track pushes the magnets on the train. For the launch to work, the change in magnetic field must change faster and faster, as the train accelerates - in a "train accelerator". Of course, also the brakes are magnetic, like the brakes in Kanonen. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 The picture shows the accelerometer data during the testing in April 2014.
