Problem 20PE

terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. Find the terminal velocity (in meters per second and kilometers per hour) of an 80.0-kg skydiver falling in a pike (headfirst) position with a surface area of 0.140 m2

Step-by-Step Solution:

Step-by-step solution Step 1 of 3 Force on a body due to gravity is, the weight of the person Here, stands for mass, stands for acceleration due to gravity. The air drag force is, Here, stands for density of the fluid, stands for drag coefficient, stands for area and stands for terminal velocity. Step 2 of 3 When the person starts to fall, the air drag starts to act in opposite direction to motion. The air drug increases with the speed. At the beginning downward weight of the person is bigger than air drag, but after some time the air drag force is equal to the weight. Terminal velocity is reached when the force of gravity is equal to the force of drag. Therefore, Rewrite the equation in terms of v,
