Which ever object has the lowest terminal velocity since it will take longer to accelerate to a higher velocity. Galileo showed that dissimilar object fall at similar rates and in the absence of air both objects would fall at an identical rate.

### How fast is terminal velocity for a penny if it is in a vacuum?

If the penny is in a vaccum, the penny has no terminal velocity because verminal velocity is when the resistance against the falling penny is equal to the force of gravity. So if it is in a vaccum, it has no forces resisting the fall, and it has no terminal velocity.

### Do a penny has the greatest velocity?

An object falling through the air will have a terminal velocity of approximately 120-140mph. The less "wind resistance" it has the faster it goes. Although the penny has less wind resistance than say, an elephant, it still is not an ideal shape for moving through the air. Being flat, it can flutter, spin, 'float', etc, and that will slow it down.

### When is terminal velocity good?

Based on two classes' worth of research on terminal velocity I'd say it's good for keeping some falling objects from reaching a speed that will, literally, be "terminal" (fatal) to whomever it hits. I was researching the myth behind whether or not a penny dropped off a tall building will kill some unlucky pedestrian below. All of my sources say it's impossible for said penny to do more than sting the person (barring them being hit in the eye or them somehow swallowing it), and the reason for this is terminal velocity.

### What would happen if you dropped a penny off the Empire State Building and it made it to the ground?

If you drop a penny off the Empire State Building, it falls at its own terminal velocity after falling about 200+ metres (that's a guess but it's around 200). A penny's terminal velocity is roughly half of a falling person's terminal velocity. A falling skydiver will reach a maximum of around 130mph, so a penny will fall at approximately 65mph.

### Why do some objects fall through the air at a diffrent rate then others?

The terminal velocity will depend on the mass (greater mass = more terminal velocity) and on the air resistance, which depends greatly on the surface are (more surface area = less terminal velocity). 2nd Answer: I believe that objects of differing mass fall at the same rate if you exclude air resistance. I remember the penny and the feather in an evacuated cylinder hitting the cylinder bottom at exactly the same time.

### If a penny dropped from a high distance would it kill you?

If it dropped from a high enough distance, it would if its terminal velocity were higher than the speed necessary to kill a person. Since coins are small and more aerodynamic, the terminal velocity would be higher than a larger, flatter object, making it sort of like a bullet. The weight of a penny would be a function of it's acceleration. If the penny is still, that acceleration would be that of gravity, more or less 9,8 m/s.s or 1 G. You take the mass of a penny (in kg) and multiply it by the acceleration (in m/s.s) to get the weight in Newtons (which is force). So, a falling penny would be going 9,8 m/s faster every second before reaching its terminal velocity. The main point is the final velocity will be very high since it's a small and for all practical purposes, an aerodynamic object and therefore the kinetic energy will be very high as well. So will the force, which depends on the acceleration and the Work, which will be the very high transference of energy from the penny to somebody's head.

### If i dropped a penny off an airplane and it hits your head can it kill you?

I say NO. If you mean it is dropped and falls vertically. Discover Channel's "Myth Busters" tried to determine if a bullet would kill you if it was fired directly vertical and falls on its own. The bullet or penny would fall at terminal velocity which is about 120mph. However, they will tumble which slows them down more. This velocity and their mass is not enough to kill you.

### Can you use a penny to fit full your car battery terminal?

Yes, in an emergency, but you really need to replace the worn battery cable terminal.

### A penny that was dropped hit the ground in 4.5 seconds what was the velocity of the penny?

Simply use the expression v = gt g = 9.8 m/s^2 and t given as 4.5 s So velocity with which the penny hits the ground will be 44.1 m/s

### How is terminal velocity reached?

This is an interesting situation. First of all we have to understand the nature of forces possible acting on the drowning body in a liquid medium. 1) weight of the body Mg acting always downward 2) buoyant force which equals to the weight of the displaced liquid always acting upward opposite to weight of the body. 3) As the weight Mg is more than buoyant the body there is net downward force which makes the body accelerated within the liquid medium hence sets in motion. 4) now due to movement of body in the liquid there comes the viscous drag due to viscous nature of liquid. Viscous drag is always opposite to the direction of motion of body in the liquid. More beautiful point is that this viscous drag ,according to Stokes's formula, is proportional to the speed of the body. Hence viscous drag gradually increases. At one stage the upward viscous drag becomes exactly equal to the net downward force. So now no force is acting on the already moving body. By Newton's first law of motion, every body continues in its uniform motion unless compelled by any external force. Hence uniform motion there after. So maximum velocity which is named terminal velocity. Very interesting scientific explanation! Isn't it?
