So i totally didnt get the stuff to measure shit, so I figured id make it up... help me out plz?

the paper goes like this...
~~~~


Procedure: Measure the height of slide and base of the slide.

Measured Height: ______
Measured Base Length along ground: ________

Use your already measured angle and the data above to calculate the lenghth of the Incline. Show your work (including equation) in the space below and report your answer with units.

                                                     Calculated Incline Length ____________

Use the data above to calculate the theoretical angle of the slide Show your work (including equation) in the space below and report your final answer with units.

                                       Calculated Angle: _______


~~~~~
We were supposed to roll a ball down the slide (flat)

Heres my data:


Length of slide (measured): 2.6m
Average Time: 2.54
Average Speed: 1.02m/s
Velocity (final): 2.1 m/s
Measured Acceleration .806m/s^2
Calculated g force = .082 g's
Angle= 69 degreese
Theoretical Acceleration: .77m/s^2

Karmaz for like a week for an answer!!
Im stuck!


Ive been mad swamped this week and this is a 37 page packet (epic fail.)

Fill in the blanks?

This assignment makes no sense though. It asks you to calculate something you already measured?

However, if you have already measured the incline length, just take that times the cosine of 69 (make sure calculator is on degrees) to find the horizontal length, and the sine of 69 to find the vertical length.

I can't help you with the rest, since obviously working from what the above will give you the same values you already measured.

I need help making up a bullshit height, that fits, and a measured base length along the ground, also made up, but that kind of fits



I figure if you can find something that can fit you would have discovered the Calculated Incline length and calculated angle...


The height and angle have to be able to fit into 69 degree angle

I dont think I know how to do the above...

ya seriously. just use cos69=x/y, where Y is equal to your measured length of the slide. multiply, and bingo. you have X.

Edit: It is somewhat obvious that the 69 degree angle is not the one I was thinking of.

Use sine to find the horizontal, and cosine to find the vertical.

It should be:

H: 2.427
V: .9317

Tsk, tsk: Trig should be required for all sophomores.

it doesnt because i havent measured

We were supposed to measure the height with a ruler and base length with a ruler

and then take those values to determine the incline length, and the angle


It would be EASY if I had the measurements, but I dont, so I need to make up "Measurements" that end up making my calculations close...

get it kind of?

So 69 degrees and 2.6 meters are fabricated as well?

If they aren't, then you are fine.

Here:

Procedure: Measure the height of slide and base of the slide.

Measured Height: ______ (.9317m) however many sig figs you use
Measured Base Length along ground: ________ (2.427m)

Use your already measured angle and the data above to calculate the lenghth of the Incline. Show your work (including equation) in the space below and report your answer with units.

(2.427)2+(.9317)2=(some value)

Take the square root of (some value), and you have the exact theoretical length.

                                                     Calculated Incline Length ____________square root of (some value) in meters

Use the data above to calculate the theoretical angle of the slide Show your work (including equation) in the space below and report your final answer with units.

Divide .9317 by the calculated incline length.

Use arccos or cos-1

Find that it is near 69.

Be done.

                                       Calculated Angle: _______Something near 69

Edit: Which angle on the triangle do they want?

If the right angle is the lower right corner, the one above it, or on the left.

The first one is 69, and the other 21.

If they mean the second, then use arcsin or sin-1

thats seriously good stuff and i will karmaz but where I went and bolded, what unit is that and where did you get it?

That is probably a stupid question but I am beat and can barely thing i have shit racing around my mind

edit: nm just saw other post
double edit:

Wow, im fucking retarted, I had to open my eyes read and not blink, I get it now dude...


btw, im not a sophomore, im a freshman... still 16 though (held back in 5th for not coming to school enough)

There, where I bolded. It is meters.

Edit: Lol, I need to read better as well.

Its okay, its late...

for  fun this is a whole section that I basically gave up on...


Problem: Predict the maximum centripetal force and compare it to the measured g-force. Also compare G forces on different parts of the ride.
(Im using a swing)

Procedure: The maximum centripetal acceleration occurs where the velocity is fastest. This is at the bottom of the swing when the ride is swinging at its maximum amplitude. The time for the swing (meter stick) to pass the bottom-most point can be measured using a stopwatch. Put a meter stick evenly between your partner and the chain on the swing while riding the swing. Start timing when one end of the meter stick passes the bottom and stop timing when the other end of the meter stick passes the bottom. The radius is measured from the top pivot point )point of rotation) to the place you are holding the accelerometer. You can determine this by measuring with the meter stick.


Can this data be fabricated?
jw if I can, i saw a lot of words and gave up

It's too late and I remember too little of rotary motion to do this. I'm not sure the data can be fabricated.

yeah, its definately cool


this totally sucks, I cant wait for tomorrow to be over (i get to fly to philly on thursday and hang out with all my friends)

all of my teachers have swamped me this week.

thanks, and mad karmaz for anyone willing to give the fabrication of the rotary swing shit a try...
