Suppose that the resistive force of the air on a skydiver can be approximated by f = - bv2. If the terminal velocity of an 82.0 kg skydiver is 33.4 m/s, what is the value of b (in kg/m) ?

The value of b 0.7351 kg/m

Explanation:

Given that;

Mass of sky diver = 82 kg

Velocity = 33.4 m/s

f = - bv²

It is a resistance force, therefore the negative sign is ignored.

since; f = mg

∴ mg = bv²

b = mg / v ² ... (1)

At terminal velocity a = 0

Put parameters in (1)

b = (82 * 10) / (33.4) ²

b = 820 / 1,115.56

b = 0.7351
