A ball is thrown verticaly
You just need to think about you throwing a ball in the air. When you throw a ball, it’s only logical that at some point it stops and then comes back down to you. So, the velocity at the maximum height(the point where it turns around) is zero!
Now, the acceleration is a bit more tricky but quite easy too! Which is the force that tries to bring the ball back to you? Well, it’s the force that tries to keep you on the ground; it’s dear old gravity! But, does it change depending on where the ball is located? No. But, we know that the gravitational acceleration is approximately 9.8m/s^2 and, as I said, it does not change. So, at maximum height, the acceleration is the gravitational acceleration!
