first you should solve for velocity by equating the normal and centripetal force then solve sin theta using the normal vanishes at the point where it leaves the surface and then put it all together in the energy conservation law mgh + (mv^2)/2= mvR then solve for h!

i think unable to find the inverse of the theories that we have made from the nature ,i.e. anti gravity theories, randomness theories make us to lead no where and finally we'll come to uncertainty theory and the things will be totally left out for experimental data!:confused:

i think you should recheck your answer,please see h'(0) = -2:smile:

i think the functions is g(x) <=f(x)<=h(x) has slope [g(x) at x=0 ] = 2 and slope [h(x) at x=0 ] = -2 however i think the function is too many in between so the question is not relevant [ i think].

thanks a lot dr greg that explains a lot.

how come photons have four momentum in what conditions does it have four momentum? c

does particles having more than the speed of light as tachyons only have four momentum or every thing has four momentum??

i heard that speed of light was the upper limit of the velocity but in Cerenkov Radiation the particle is going in speed more than that of light and if charged particles do so in a medium doesn't it show cooling effect? can anyone answer this questions please...
