Calculating time to reach certain velocity with drag force

WebTerminal Velocity, however, means the top speed an object can achieve when it falls through the air. When an object (like a skydiver) falls freely through a medium, such as water or air, the force of gravity pulls it toward Earth. As the object falls, its velocity increases as it accelerates toward Earth.

WebThe terminal velocity depends on many factors including mass, drag coefficient, and relative surface area and will only be achieved if the fall is from sufficient altitude. A typical skydiver in a spread-eagle position will reach terminal velocity after about 12 seconds, during which time they will have fallen around 450 m (1,500 ft). [4] WebOnce the upward force of air resistance upon an object is large enough to balance the downward force of gravity, the object is said to have reached a terminal velocity. The terminal velocity is the final velocity of the object; the object will continue to fall to the ground with this terminal velocity.

WebIf, instead, she orients her body with her head straight down, she falls faster, reaching a terminal velocity of 150 mph (220 ft/sec). Since Julie will be moving (falling) in a downward direction, we assume the downward direction is positive to simplify our calculations. Julie executes her jumps from an altitude of 12,500 ft. WebMay 25, 2007 · The combination of these two forces causes a raindrop to reach a terminal velocity when the drag force is approximately equal to the weight of the raindrop. At this point, a raindrop experiences no further acceleration and therefore falls at a constant velocity. The magnitude of the terminal velocity of an object is also affected by its ...
