Question

question 10 of 10 a football is kicked with a velocity of 31 m/s at an angle of 41°. what is the balls acceleration in the vertical direction as it flies through the air? a. 0 m/s² b. -20.3 m/s² c. 23.4 m/s² d. -9.8 m/s²

Explanation:

Step1: Identify the force acting vertically

The only force acting on the football in the vertical - direction while it is in the air is gravity.

Step2: Recall the acceleration due to gravity

The acceleration due to gravity near the surface of the Earth is approximately $g=- 9.8\ m/s^{2}$, where the negative sign indicates the direction is downward. This is the acceleration of the ball in the vertical direction.

Answer:

D. -9.8 m/s²
