Answer:
m(∢G)=63°
m(∢H)=27°
Step-by-step explanation:
m(∢G)=3x+6
m(∢H)=2x-11
m(∢G)+m(∢H)=90°
3x+6+2x-11=90°
5x=95°=>x=19°
m(∢G)=3*19°+6°=63°
m(∢H)=2*19°-11°=27°
Answer:
![F_{c}=m\frac{v^{2}}{L}](https://tex.z-dn.net/?f=F_%7Bc%7D%3Dm%5Cfrac%7Bv%5E%7B2%7D%7D%7BL%7D)
Step-by-step explanation:
The centripetal force is product of the mass times the centripetal acceleration
![F_{c}=ma_{c}](https://tex.z-dn.net/?f=F_%7Bc%7D%3Dma_%7Bc%7D)
Now, the ![a_{c}=\frac{v^{2}}{R}](https://tex.z-dn.net/?f=a_%7Bc%7D%3D%5Cfrac%7Bv%5E%7B2%7D%7D%7BR%7D)
- v is the tangential velocity
- R is the radius of the circle (L in our case)
Therefore, the centripetal force will be:
![F_{c}=m\frac{v^{2}}{L}](https://tex.z-dn.net/?f=F_%7Bc%7D%3Dm%5Cfrac%7Bv%5E%7B2%7D%7D%7BL%7D)
It has a positive sign because the centripetal force points toward the center of the circle.
