Assuming that there is no velocity in the horizontal direction, then the velocity at that instant is zero.
The vertical velocity is 0. The horizontal velocity is constant during the entire trajectory (and may be zero).

Temperature is the measure of how fast particles are moving in an object.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
Temperature.
Speed. (not velocity)
they are different words with the same meaning.
