A small mass m slides without friction along the looped apparatus shown in Fig
Homework Answers
I assume h is measured from the bottom of the loop, so the PE going into the mass is h-2r measured at the top. So that is equal to KE at the top.
mg(h-2r)=1/2 m v^2
so solve that for v^2
Now, at the top, the force on the track is mg-mv^2/r, and that to stay on the track must be non negative.0<mg-mv^2/r
so put in v^2 from before, and solve for h.
