Maximum kinetic energy in projectile motion

[Elena14]

Finding the maximum kinetic energy in a simple parabolic projectile motion requires us to find the maximum velocity. I know that the velocity will be maximum at two points, the point of projection and point of return.

So there must be two points where the kinetic energy is maximum. But my textbook only says it is maximum at the point of projection. Why is that?

Air resistance has been neglected in the question.

Then I believe you are right.
