The saw will tip towards the heavy boy. they are centered on the main pivot point so weight dosnt matter but as they go out. mass and weight will determin if the saw moves or not
Answer:
50 degrees
Explanation:
complimentary angles will give you the same range
gravitational potential energy is given by formula
![U = mgh](https://tex.z-dn.net/?f=U%20%3D%20mgh)
here we need to compare the gravitational potential energy of stone 2 with respect to stone 1
so we will say
![\frac{U_2}{U_1} = \frac{m_2gh}{m_1gh}](https://tex.z-dn.net/?f=%5Cfrac%7BU_2%7D%7BU_1%7D%20%3D%20%5Cfrac%7Bm_2gh%7D%7Bm_1gh%7D)
![\frac{U_2}{U_1} =\frac{m_2}{m_1}](https://tex.z-dn.net/?f=%5Cfrac%7BU_2%7D%7BU_1%7D%20%3D%5Cfrac%7Bm_2%7D%7Bm_1%7D)
given that
![m_2 = 4 m_1](https://tex.z-dn.net/?f=m_2%20%3D%204%20m_1)
now we have
![\frac{U_2}{U_1} = 4](https://tex.z-dn.net/?f=%5Cfrac%7BU_2%7D%7BU_1%7D%20%3D%204)
the answer is b trust me its b
