im assuming that delta and psi are changing since it is coming down the paraboloid and the paraboiloid is spining due to revolution. Should i use polar coordinates or cartesian form?
Homework Statement
A particle of mass m is placed on the inside of a smooth paraboloid of revolution whose equation is
cz = x2 + y2 , where c is a constant, at a point P which is at a height H above the horizontal x-y plane.
Assuming that the particle starts from rest (a) find the speed...
