Colors seen on the cover of our physics book result from color is due to Subtraction.
What is physics of color subtraction?
- Some visible spectrum wavelengths are intentionally removed during the subtraction procedure.
- For instance, the yellow filter transmits the green and red colors while blocking the blue.
- Red and blue are transmitted while the green is blocked by the magenta filter.
- Blue and green are transmitted while red is blocked by the cyan filter.
- Subtractive mixing gets its name from the fact that when colors are mixed, wavelengths are removed from what we see because each paint absorbs some of the wavelengths that the other paint reflects, leaving us with less wavelengths afterward.

Answer:
(a) Bus will traveled further a distance of 40 m
(b) It will take 7.5 sec to stop the bus
Explanation:
We have given initial velocity of the bus u = 24 m/sec
And final velocity v = 16 m/sec
Distance traveled in this process s = 50 m
From third equation of motion we know that ![v^2=u^2+2as](https://tex.z-dn.net/?f=v%5E2%3Du%5E2%2B2as)
![16^2=24^2+2\times a\times 50](https://tex.z-dn.net/?f=16%5E2%3D24%5E2%2B2%5Ctimes%20a%5Ctimes%2050)
![a=-3.2m/sec^2](https://tex.z-dn.net/?f=a%3D-3.2m%2Fsec%5E2)
(a) Now as the bus finally stops so final velocity v = 0 m/sec
So ![v^2=u^2+2as](https://tex.z-dn.net/?f=v%5E2%3Du%5E2%2B2as)
![0^2=24^2-2\times 3.2\times s](https://tex.z-dn.net/?f=0%5E2%3D24%5E2-2%5Ctimes%203.2%5Ctimes%20s)
s= 90 m
So further distance traveled by bus = 90-50 =40 m
(b) Now as the bus finally stops so final velocity v= 0 m/sec
Initial velocity u = 24 m/sec
Acceleration ![a=-3.2m/sec^2](https://tex.z-dn.net/?f=a%3D-3.2m%2Fsec%5E2)
So time ![t=\frac{v-u}{a}=\frac{0-24}{-3.2}=7.5sec](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bv-u%7D%7Ba%7D%3D%5Cfrac%7B0-24%7D%7B-3.2%7D%3D7.5sec)
B. Amplitude
It is the maximum distance from the equilibrium point of the pendulum.
