The highest velocity of an airgun is that of Evanix AR6 pistol which is 1000 fps.
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
In that case, the velocity is zero.
The vertical velocity is zero at the highest point. It has ceased moving upward and will begin moving downward. Gravity and air resistance will have negated the original vertical velocity (y-component). So the velocity at the highest point has only a horizontal or x-component.
The highest velocity of a bird is approximately 200 miles per hour. This speed is reached by the peregrine falcon when it dives for hunting purposes.
A the highest point its velocity will be zero.
At the highest point, there's an instant when the motion is changing from upward to downward. At that exact instant, the speed is zero, and that's zero velocity.
