Question

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

Expert Solution

Step 1

Given mass of skydiver is 66.0 kg and 93.0 kg.

Air density = 1.23kg/m³

Drag coefficient = 0.7

Area = 0.18 m²

Formula for terminal velocity is $\sqrt{\frac{2 m g}{ρ A C_{d}}} w h e r m i s m a s s o f f a l l i n g o b j e c t, g i s a c c e l e r a t i o n d u e t o g r a v i t y, ρ i s a i r d e n s i t y, A i s a r e a a n d C_{d} i s d r a g c o e f f i c i e n t .$
