who can tell me air resistance formula?

Question

anonymous · Answer

Resistance (Ohms) = Voltage (v) / Current (I)

anonymous · Answer

is that??

anonymous · Answer

oh cool now i have to translate it to lithuanian Aiko xDD

anonymous · Answer

so idk

anonymous · Answer

its for electric resistance

anonymous · Answer

for air resistance F(air) = -cv^2

anonymous · Answer

does answear is 800 Newtons?

anonymous · Answer

c is constant which depends upon the shape of the body

anonymous · Answer

hmm okay, can you plz try to slove this task: 80 kg cylinder is set evenly. Calculate the applied force of air resistance?

anonymous · Answer

i think answear is 800 Newtons but idk

anonymous · Answer

where is that question

anonymous · Answer

80 kg cylinder is set evenly. Calculate the applied force of air resistance?

anonymous · Answer

oh wait

anonymous · Answer

anonymous · Answer

80 kg weight of the balloon set evenly. Calculate the applied force of air resistance.

anonymous · Answer

okay, thank you but can you try slove that task?

anonymous · Answer

80 kg weight of the balloon set evenly. Calculate the applied force of air resistance.

anonymous · Answer

is the balloon moving?

anonymous · Answer

yeah

anonymous · Answer

its velocity?

anonymous · Answer

no, we need to find out air resistance force

anonymous · Answer

the formula includes velocity squared

anonymous · Answer

ummm, but there's nothing said about velocity

anonymous · Answer

can you state the question as it is?

anonymous · Answer

Calculate the applied force of air resistance.

anonymous · Answer

weight = mass * gravitational speed;  wight =80kg*10m/$$s{2}$$= 800 Newtons

anonymous · Answer

maybe something like this? sorry i dont know how to write formula cuz i'm from lithuania and it's difference words in english

anonymous · Answer

The air resistance = weight of balloon because it is not accelerating.

anonymous · Answer

actually you did not state the question fully, you should have mentioned that the balloon is falling with terminal velocity

anonymous · Answer

you mean that this task answear is 80 Newtons? or what?

anonymous · Answer

equal to its weight 800N

anonymous · Answer

I had to guess that "set evenly" means constant velocity.

anonymous · Answer

answear 800N? :I

anonymous · Answer

yup

anonymous · Answer

really? cool then i sloved it correct! thank you ^^

anonymous · Answer

you are welcome
