What is the kinetic energy of a projectile at highest point ?

The kinetic energy of a projectile at the highest point is-

A particle is attached to a string and the other end of the string is attached to a fixed support. In order to just complete the vertical circular motion, what should be the ratio of the kinetic energy of the particle at its highest point of that at its highest point to that at its lowest point?

Acceleration of a particle under projectile motion at the highest point of its trajectory is :

Acceleration of a particle under projectile motion at the highest point of its trajectory is :

A particle is projected at 60^@ to the horizontal with a kinetic energy K. The kinetic energy at the highest point is

A particle is projected at pi/4 to the horizontal with a kinetic energy K. The kinetic energy at the highest point is
