Heya!
When a body is projected vertically upwards. Its velocity get decreasing. At the highest point , its velocity get zero and its kinetic energy also become zero.
The expression for it:
Let the mass of the body is m .
Initial velocity = u
final velocity= 0
Then,
K.E.( at the highest point) = 1/2*m*v^2
= 1/2*m*0
=0
Hence, kinetic energy of the body also becomes zero.
Hope it helps u.

Hey!!!!
Kinetic energy = 1/2 * mass * velocity
When velocity = 0
Kinetic energy = 1/2 * mass * 0 = 0
But this is not enough
The final statement is
The kinetic energy keeps on decreasing and becomes zero when the velocity becomes zero. As energy can neither be created nor be destroyed, the kinetic energy actually gets converted into gravitational potential energy of the body. The gravitational potential energy = mgh and the kinetic energy = 0
HOPE THIS HELPS YOU :)
