Answer:
Step-by-step explanation:
From the right triangle attached in the picture,
sine ratio for the angle X,



cosine ratio for the angle X,



tang ratio for the angle X,


First multiply the equation by r
f*r=(mv^2)
then divide by m f*r/gm=v^2
put the equation all together you get v=sqrt(FrgM)/gM
