The kinematics allows to find that the result, which happens with the passengers who look back in a punt, is:
- The acceleration is great, for which they must be held because they cannot avoid moving and the eyes must be held.
Kinematics studies the motion of bodies, finding relationships between position, velocity and acceleration, let's use the relationship
v = v₀ + a t
Where v is the velocity, v₀ the initial velocity, at the acceleration and t the time
In this case, as it comes out of rest, the initial velocity is zero.
a =[tex]\frac{v}{t}[/tex]
Let's reduce
v = 200 mph ([tex]\frac{5280 ft}{1 mi}[/tex]) ([tex]\frac{1h}{3600 s}[/tex] ) = 293.33 ft / s
Let's calculate
a = 293.33 / 1.5
a = 195.56 ft / s²
Let's find the relationship of this acceleration and the gravity acceleration.
a / g = 195.56 / 9.8
a = 20 g
The human body loses consciousness for acceleration greater than 6g and cannot move for acceleration much less than 4g, without special suits.
As the acceleration of the plane is very fast, people do not have the strength to stop their feet, so they have to be held, the garlic is held by the eyelids, but the force is felt on them, in some cases some small ones are broken veins.
In conclusion with the kinematics we can find that the result, which happens with the passengers who look back in a clearance is:
- The acceleration is great, for which they must be held because they cannot avoid moving and the eyes must be held.
