In a stable, belly to earth position, terminal velocity of the human body is about 200 km/h (about 120 mph). A stable, freefly, head down position has a terminal speed of around 240-290 km/h (around 150-180 mph).
How far will an object travel after ten seconds if it is dropped into a bottomless pit? Explanation: Since the object is dropped, the inital velocity is zero. Gravity is the only acceleration, the time is ten seconds, and the distance at which the object travels is unknown.
The formula for free fall:
Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= frac{1}{2}gt^2. v²= 2gh.
Answer 1: Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.
And the problem was, how long does it take for a person to fall 4000 feet if their terminal velocity is 120? So to determine how long it takes to get to terminal velocity… (Or is it 176 / 9.8 squared?) So 21.72 + 5.42 = 27.14 seconds to fall that distance.
Final Velocity Formula
vf=vi+aΔt. For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity.
Estimate how fast you will go on your trip. Then, divide your total distance by your speed. This will give you an estimation of your travel time. For example, if your trip is 240 miles and you are going to be drive 40 miles an hour, your time will be 240/40 = 6 hours.
