You throw a glove straight upward to celebrate a victory. Its initial kinetic energy is K and it reaches a maximum height H. What is the kinetic energy of the glove when it is at the height H/2?

If the PE is half, the KE must have lost half.

Can you please explain it a little more. I still don't understand it.

first find the constant. AT the beginning, PE is zero, and KE is K
when at half height, PE=1/2 K

Ok thanks. Can 1/2K also be written as K/2?
