what is the vertical acceleration of a dart that is launched horizontally with an initial velocity of 2.3 m/s?\n-9.8 m/s²\n0 m/s²\n2.3 m/s²\n9.8 m/s²

Answer

Explanation:

Step1: Identify the force acting vertically

When a dart is launched horizontally, the only vertical - acting force is gravity.

Step2: Recall the acceleration due to gravity

The acceleration due to gravity near the surface of the Earth is approximately $g = 9.8\ m/s^{2}$ in the downward direction. In the standard coordinate system where up is positive and down is negative, the vertical acceleration $a_y$ of an object in free - fall is $a_y=- 9.8\ m/s^{2}$.

Answer:

$-9.8\ m/s^{2}$
