Answer:
The distance is 19.58 m.
Explanation:
Given that,
Mass = 3.0 kg
Radius = 1.3 m
Angular speed = 6.8 rad/s
Angle = 24°
Acceleration of gravity = 9.81 m/s²
We need to calculate the distance
Using formula of kinetic energy
Total Initial kinetic energy,
![K.E = \dfrac{1}{2}(mv^2+I\omega^2)](https://tex.z-dn.net/?f=K.E%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%28mv%5E2%2BI%5Comega%5E2%29)
![K.E = \dfrac{1}{2}(mv^2+mr^2\omega^2)](https://tex.z-dn.net/?f=K.E%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%28mv%5E2%2Bmr%5E2%5Comega%5E2%29)
![K.E =\dfrac{(mr^2+mr^2)\omega^2}{2}](https://tex.z-dn.net/?f=K.E%20%3D%5Cdfrac%7B%28mr%5E2%2Bmr%5E2%29%5Comega%5E2%7D%7B2%7D)
....(I)
Now, Total potential energy
![P.E=mgs\sin\theta](https://tex.z-dn.net/?f=P.E%3Dmgs%5Csin%5Ctheta)
....(II)
Equating equation (I) and (II)
![mr^2\omega^2==mgs\sin24^{\circ}](https://tex.z-dn.net/?f=mr%5E2%5Comega%5E2%3D%3Dmgs%5Csin24%5E%7B%5Ccirc%7D)
![(1.3)^2\times6.8^2=9.81\times s\times\sin24^{\circ}](https://tex.z-dn.net/?f=%281.3%29%5E2%5Ctimes6.8%5E2%3D9.81%5Ctimes%20s%5Ctimes%5Csin24%5E%7B%5Ccirc%7D)
![s = \dfrac{1.3^2\times6.8^2}{9.81\times\sin24^{\circ}}](https://tex.z-dn.net/?f=s%20%3D%20%5Cdfrac%7B1.3%5E2%5Ctimes6.8%5E2%7D%7B9.81%5Ctimes%5Csin24%5E%7B%5Ccirc%7D%7D)
![s=19.58\ m](https://tex.z-dn.net/?f=s%3D19.58%5C%20m)
Hence, The distance is 19.58 m.
It would be metric
this is the most popular, or most famous technique of measuring(In USA)
hope that this helps you! =)
