Altitude Maximum Deceleration, Value, Velocity at Impact

In order to calculate the Altitude Maximum Deceleration of Solid Metal Sphere we need to have the value of Velocity in km/s with which the Metal Sphere is entering the Earth's atmosphere.

 

 

Also, we require the angle and the orientation (Below or above) the local horizontal with which its entering.

 

We must also know the Sphere Diameter in m (meters) the Drag Coefficient of Sphere CD, the Density in kg/m^3 and the Exponential Atmospheric Temperature in Kelvin. Furthermore, we must assume a value of Density row0.

 

Computing this, the following Parameters are acquired.

Ballistic Parameter m/ CD S

Z =g0/RT value
