If a ball rolls in a semicircular track starting from one end of track,( the track is kept vertical) and if radius of ball is r and radius of track is R
is this expression correct? (When ball reaches lowest point)
##mg(R-r)=\frac{1}{2}I_0\omega^2 + \frac{1} {2}I\omega_1^2+\frac{1}{2}mv^2##
where ##I_0## is the moment of inertia about centre of track since the ball moves in a circle and moment of inertia is mr^2
The second is for rotation of ball
the third is translational kinetic energy
what changes should I make if R is very very larger than r?
