![]() Note: For Speed or Velocity conversions, US Customary Units and the Imperial System are equivalent. ![]() Additionally, it ignores wind resistance, aka 'terminal velocity'. The more interesting question is why it's times two: If you accelerate for 1 second, your averagespeed over that time is increased by only 9.8 / 2 m/s. Time to splat: sqrt ( 2 height / 9.8 ) It's the square root because you fall faster the longer you fall. You actually fall a bit less distance, because you should use the average speed for that second, not the final speed. calculista Answer: Part 1) The speed is Part 2) Step-by-step explanation: Part 1 What is this speed on feet per second we know that 1 hour60 min 1 min60 sec so 1 hour60603. After two seconds, you're falling 19.6 m/s, and so on. Second 6 - Fall 192 per second, total 672 feet. Free-fall, which is injurious, should be faster than that. Second 5 - Fall 160 per second, total 480 feet. per round (6 sec.), or at a speed of 10 fps without suffering damage. ![]() When terminal velocity is reached, the downward force of gravity is equal to the sum of the object's buoyancy and the drag force. Feather Fall allows one to fall at 60 ft. What is its speed 5 seconds later a) 50 m/s b) 40 m/s c) 30 m/s d) 20 m/s e) 10 m/s A rock is dropped off a cliff. The following tables provide a summary of the Speed or Velocity units (Per Hour, Per Minute, Per Second and Per Millisecond) within their respective measurement systems. Terminal Velocity Definition Terminal velocity is defined as the highest velocity that can be achieved by an object that is falling through a fluid, such as air or water. At one instant an object in 'free fall' is moving upward at 30 meters per second.
