# A skydiver can be modeled as a rectangular “box” with dimensions What is his terminal speed if he falls feet first? Use for the drag coefficient.

The terminal speed if he falls feet first is

See the step by step solution

## Step 2 : Calculation

The formula for terminal velocity is given by:

here,

mass of the body

gravitational acceleration

density of air

= Projected area

c = Drag Constant

The density of air is

Projected area :

## Step 3 : Continuation of calculation

Putting the values we get,

Therefore, the terminal velocity is

## Step 4 : Final answer

The terminal speed if he falls feet first is
