The terminal velocity of a human being is 200 km/hr, and it takes about 12 seconds to achieve this. This calculation considers for air friction of course. What would a person’s speed be if they free fell for 12 seconds instead (no air friction present)?
The average skydiver, with parachute unopened, weighs 80 kg. Depending on the orientation of theskydiver, whether vertical (upright)or horizontal (lying flat), what are the minimum and maximum terminal speedsattained at an altitude of 2000 m
A 66.0 kg and a 93.0 kg skydiver jump from an airplane at an altitude of 5.95 ✕ 103 m, both falling in the pike position. Assume all values are accurate to three significant digits. (Assume that the density of air is 1.21 kg/m3 and the drag coefficient of a skydiver in a pike position is 0.7.)
If each skydiver has a frontal area of 0.18 m2, calculate their terminal velocities (in m/s). (Enter the magnitudes.)
66.0 kg skydiver m/s
93.0 kg skydiver m/s

- A skydiver will reach a terminal velocity when the air drag equals his or her weight. For a skydiver with a large body, turbulence is a factor at high speeds. The drag force then is approximately proportional to the square of the velocity.
