What is the vertical acceleration of a dart that is launched horizontally with an initial velocity of 2 point 3 m/s ?

Launching the dart horizontally gives it an initial vertical velocity of zero, but gravity still accelerates it downward. Taking upward as positive, the vertical acceleration is −9.8 m/s². Therefore, the correct choice is negative 9 point 8 m/s squared.
