Answer:
The braking distance would be about nine times as long (assuming that acceleration during braking stays the same.)
Explanation:
Let denote the initial velocity of the vehicle (
or
) and let
denote the velocity of the vehicle after braking (
). Let
denote the braking distance.
Assume that the acceleration during braking are both constantly in both scenarios. The SUVAT equations would apply. In particular:
.
Since <em> </em>(the vehicle has completely stopped), the equation becomes
.
Assuming that (braking acceleration) stays the same, the braking distance
would be proportional to
, the square of the initial velocity.
Hence, increasing the initial speed from to
would increase the braking distance by a factor of
.
Passengers in an aircraft are subject to the Normal and Gravity Force acting on them at a low 'orbit', so tiny that it can be many times compared to the same surface of the earth when speaking in general terms.
In a high orbit space vehicle or in the same space, said force decreases considerably or simply disappears, generating the sensation of weightlessness.
Remember that the Force of Gravity is given under the principle
Where,
G = Gravitational Universal constant
M = Mass of the planet
m = mass of the object
r = Distance from center of the planet
When the radius grows considerably the gravitational force begins to decrease.
