Here's a coment excerpt from clue's forum

Again: for a non-constant deceleration you just can't take the "average" ((initial + final) / 2) velocity, multiply it by the time and obtain the correct total braking distance.

To calculate it, you need another value of the velocity: average by time. But this is the same thing as to calculate the braking distance (by solving the Cauchy problem for a non-linear equation).

Most of those 254 s (having supposed that Curiosity is real) the velocity might be remarkably lower than the mean arithmetic of initial and final values -- because of a huge drag force at initial stage. To estimate it, you need real numbers about the martian atmosphere density at 100 km and the aerodynamic quality (C_x, C_y) of the spacecraft.

The gatekeepers appearing on this forum and others use the tactic of making you prove the numbers in order to force them to admit the official story [gee where have we heard this before : ) ]...is wrong.

NASA/JPL went with the blistering insertion ...parachute deploy [note this is to make you focus on the closure....which is the barking thrusters ...very much like the CGI alien craft over LA in the Movie - Battle : Los Angeles/hint hint : )]

7 minutes of Terror is some form of Orwell 1984 template/fake war on terror....the Elite show their intention and boast continually via MSM/MK ULTRA.
This is exactly what Curiosity mission is....world wide
MK ULTRA...Imperial conditioning....with Gatekeeper agents serving their masters by controlling talking points.

Simple common sense says the story they [NASA/JPL] are selling is BS,....and the Time* interval they used to shock us with is the smoking gun its complete nonsense...
like aviation fuel/carbon based fire brings buildings down at near freefall speed.
returning to key points:
They can CGI this....The system does False Flag for the socio trauma needed in MK ULTRA conditioning.
Run the lie and make it outrageous...the more the better,
like Bin Ladens fake death.
Mars Atmosphere density,....the insertion speed and Time are the evidence its complete nonsense...
the sell is the visual CGI with the sheeple slowed to focus by the parachute and burster rockets to convey control for the crypto socio sexual climax of the cable landing.
Most people are too dumbed down to consider the insertion speed/Time and lack of Atmosphere density.
They are moved in thought to image after image of control and then success...with NASA/JPL actors cheering like super bowl touchdown.
I used the excerpt from clue's forum to link viewers here to other sites working this NASA/JPL lie.
here...they will find 50 pages of evidence of how NASA faked the Apollo Moon landings.
