Very simple question (basic kinematics)

[QUOTE="Diego Fernandez, post: 4950152, member: 535657"] [h2]Homework Statement [/h2] I'm taking my first basic physics course and I came across this simple question (which I got the wrong answer apparently). The question was this: what is the velocity and acceleration of an object which has reached it's maximum height after being thrown directly upwards? [h2]Homework Equations[/h2] [/B] Well, you don't really need equations for this, unless you want to mathematically prove your answer. In that case: Acceleration = (Velocity - Initial Velocity) / Time Time = Distance / Average Velocity Velocity = Initial Velocity + Acceleration(Time) Distance = Initial Position + Average Velocity(Time) These are very basic Kinematic equations. [h2]The Attempt at a Solution[/h2] What I answered was that the velocity is 0 (which was correct) and that the acceleration was also 0 (which was incorrect). I went by the test a little too fast and realized my answer was most likely wrong after comparing answers with other students. The mistake I made was assuming that since it was at 0 velocity, there couldn't possibly be any acceleration whatsoever, but I did not take into account that acceleration = gravity. Since gravity is always influencing an object, there must be a rate of acceleration (-9,8 m/s). But my question is how could there possibly be an acceleration for an object which has a velocity of 0?
