Which quantities are zero when a ball reaches maximum height

[je55ica7]

A ball is thrown vertically upward. Consider the following quantities: 1)speed, 2)velocity and 3) acceleration. Which of these will be zero when the ball has reached the maximum height?

Won't all three be zero?

 

[Pseudo Statistic]

Acceleration is never 0 on Earth...
Think about it this way, it's BECAUSE of the acceleration that the velocity & speed have become 0... 'cause the ball was moving up with some positive velocity along the y axis, and the acceleration acts downwards and thus reduces it.

I see...so the velocity and speed are 0 at the max height, but the acceleration is always 9.8m/s^2?
