Question

if you throw a baseball straight up, what is its acceleration at the highest point? -9.8 m/s² -9.8 m/s 0 m/s² 0 m/s

Explanation:

Step1: Identify the force acting on the ball

The only force acting on the baseball in - air near the Earth's surface is gravity.

Step2: Recall the acceleration due to gravity

The acceleration due to gravity near the Earth's surface has a magnitude of approximately $9.8\ m/s^{2}$ and is directed downwards. At the highest - point of the ball's motion, although its velocity is 0 m/s, the acceleration due to gravity is still acting on it.

Answer:

A. -9.8 m/s²
