Following the initial impact, the car is slowed to a standstill with a maximum deceleration rate of 5 m / s ² and its brakes are then locked for a further 1.5 seconds. (bmwblog.com)
Then the system autonomously initiates braking at a maximum deceleration rate of 0.6 g. (motor-prime.com)
The team's model suggests that stems from a slower deceleration rate for Earth's spin at the time, which affected the total amount of rotational momentum in the Earth - moon system and thus how rapidly the moon's spin rate decelerates, among other things. (sciencemag.org)
