Asked by Erica

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?
Answered by bobpursley
If the PE is half, the KE must have lost half.
Answered by Erica
Can you please explain it a little more. I still don't understand it.
Answered by bobpursley
KE+PE=a constant
first find the constant. AT the beginning, PE is zero, and KE is K

KE+PE=K

when at half height, PE=1/2 K
KE+1/2 K=K
KE=1/2K
Answered by Erica
Ok thanks. Can 1/2K also be written as K/2?
