To solve this task we have to make a proportion, but firstly we have to set up all the main points : so, the distance is s=r(B), that has its <span>r=radius,B=angle in rad
velocity v=ds/dt= w(r)
Do not forget about </span> w = angular speed in rad/s and
![w1 = 1 revolution/sec = 2Pi (rad/s)](https://tex.z-dn.net/?f=%20w1%20%3D%201%20revolution%2Fsec%20%3D%202Pi%20%28rad%2Fs%29)
Now we can go to proportion
![v1=v2](https://tex.z-dn.net/?f=v1%3Dv2)
![w1*r1 = w2r2](https://tex.z-dn.net/?f=%20w1%2Ar1%20%3D%20w2r2%20)
![w2 = w1 * r1/r2 = 2w1 = 4Pi (rad/s)](https://tex.z-dn.net/?f=w2%20%3D%20w1%20%2A%20r1%2Fr2%20%3D%202w1%20%3D%204Pi%20%28rad%2Fs%29)
![w2 = w3 (which is the angular velocity of the rear wheel) ](https://tex.z-dn.net/?f=%20w2%20%3D%20w3%20%28which%20is%20the%20%20%20angular%20velocity%20of%20the%20rear%20wheel%29%20%0A)
SOLVING FOR A :
![v3 = w3 * r3 = 4pi * 14 (inch/s) = 14.66 ft/sec](https://tex.z-dn.net/?f=v3%20%3D%20w3%20%2A%20r3%20%3D%204pi%20%2A%2014%20%28inch%2Fs%29%20%3D%2014.66%20ft%2Fsec)
![v3 = 14.66 ft/sec(1 mile/5280 ft)( 3600 sec/h)](https://tex.z-dn.net/?f=v3%20%3D%2014.66%20ft%2Fsec%281%20mile%2F5280%20ft%29%28%203600%20sec%2Fh%29)
![= 9.99](https://tex.z-dn.net/?f=%3D%209.99%20)
or something about <span>10 mph --- SOLVING FOR B.
</span>I'm sure it helps!
repeated mesurement can reduce the error
it is true
if you take any mesurement repeatedly and the average is taken, the error will be less
In one of the most amazing coincidences in all of science,
the part of the electromagnetic spectrum that's visible to the
human eye is called "visible light".
Visible light is not 'divided' into anything. We mention the names
to seven of the colors in visible light. But all of the thousands of
OTHER colors that we can see are in there too, even though we
don't bother to list their names when we buzz through the rainbow
in the third grade.
