Its for my physics project and i have tried searching everywhere but couldnt find it.
It is drop zone of kings dominion and i want to find the weight of the object people are sitting on. Basically the whole circular thing.

can any1 help me?

thank you

I've had a look, can't find anything on it.

If it's for a physics project, you can get the drop speed and you know it's freefall (well I assume it is) so acceleration = gravity and you know the drop height. So why don't you plug these values into some equations and try to calculate the mass yourself? Now that would be impressive...

yea about that i had tried doing that but the thing is i dont know how to calculate for the air resistance which makes it all difficult. i calculated v0, v1, t assuming no air resistance "sigh" on me :(

Well, you know the final speed, height and you know the initial speed, from that you can get it's acceleration (it should be less than g so it will give an approximation for air resistance).

the thing is i used g as acceleration do find initial and final velocity

Yes, but if you know initial speed (0) and final speed (whatever value in m/s) and you know the height, you can use the equations of motion to get an acceleration value.

Because the final speed will be a 'real' speed attained with air resistance it will give you an acceleration which reflects it.

It's not perfect, but you should get a value for this and value with no resistance and it should give you some sort of 'grey area' to work within.

thanks bro
