Question

a ball is launched upward from the ground. the diagram shows its location at 1 - second intervals. rank the magnitude of the speed and acceleration for the three indicated locations. ball speed - magnitude only rank locations a, d, and g. smallest middle greatest ball acceleration - magnitude only rank locations a, d, and g. smallest middle greatest

Explanation:

Step1: Analyze speed of ball in free - fall

When a ball is launched upward, its speed decreases as it moves up due to gravitational acceleration. At the highest - point, the speed is 0. Point A is at the start (launch), point D is in the middle of the upward motion, and point G is near the top. The speed at the start (A) is the greatest, then at D, and the smallest at G.

Step2: Analyze acceleration of ball in free - fall

The acceleration of an object in free - fall near the Earth's surface is constant and equal to the acceleration due to gravity ($g\approx9.8\ m/s^{2}$) and acts downward. So the acceleration at points A, D, and G is the same.

Answer:

Ball Speed:
Smallest: G
Middle: D
Greatest: A
Ball Acceleration:
Smallest: All the same
Middle: All the same
Greatest: All the same
