Hello!
Remember that kinetic energy is one that is produced by the speed of a body that has mass. The equation is as follows.
![E=\frac{MV^2}{2}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7BMV%5E2%7D%7B2%7D)
Where
E=kinetic energy
m=mass
V=speed
To solve this problem we must raise the equation for the kinetic energy of the sphere and the kinetic energy of the cylinder.
for cilinder
![Ec=\frac{McVc^2}{2}](https://tex.z-dn.net/?f=Ec%3D%5Cfrac%7BMcVc%5E2%7D%7B2%7D)
for spherical shell
![Es=\frac{MsVs^2}{2}](https://tex.z-dn.net/?f=Es%3D%5Cfrac%7BMsVs%5E2%7D%7B2%7D)
as the problem indicates the kinetic energy is the same, so we can match the previous equations
![\frac{MsVs^2}{2}=\frac{McVc^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BMsVs%5E2%7D%7B2%7D%3D%5Cfrac%7BMcVc%5E2%7D%7B2%7D)
![{MsVs^2}={McVc^2}](https://tex.z-dn.net/?f=%7BMsVs%5E2%7D%3D%7BMcVc%5E2%7D)
according to the problem the masses are equal Ms = Mc
![Vs^2=Vc^2\\](https://tex.z-dn.net/?f=Vs%5E2%3DVc%5E2%5C%5C)
we apply square root on both sides of the equation
![Vs=Vc](https://tex.z-dn.net/?f=Vs%3DVc)
![\frac{Vs}{Vc} =1](https://tex.z-dn.net/?f=%5Cfrac%7BVs%7D%7BVc%7D%20%3D1)
In conclusion, if two bodies, regardless of their shape, have the same mass and the same kinetic energy, the speed of the two bodies will be the same.
Answer:
The answer is 8 units squared.
Step-by-step explanation:
Let, the angles = a, b
It is given that, a+b /5 = 24
a + b = 120 --- equation (1)
a-b/2 = 14
a - b = 28 ---- equation (2)
a = 28 + b
Now, substitute this value of b in equation (1),
28 + b + b = 120
2b = 120 - 28
b = 92/2
b = 46
Now, a = 28 + b = 28 + 46 = 74
In short, Your Angles are 74 and 46
Hope this helps!
