Question

derivation of the minimum speed of a body in vertical motion at it's highest and lowest point​

Answer 1

If the velocity 'v' of the body is such that √2gr < v < √5gr , then the body leaves the circular path and acts like a projectile. It will leave circular motion between M and H. Notes: Kinetic energy is maximum at the lowest point of the circular path and minimum at the highest point of the circular path...
