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 b, f, and i.

smallest middle greatest
tap me! tap me! tap me!
or tap here for all the same.

ball acceleration - magnitude only
rank locations b, f, and i.

smallest middle greatest
tap me! tap me! tap me!
or tap here for all the same.

Explanation:

Step1: Understand speed in free - fall

When a ball is launched upward, its speed decreases as it moves up due to gravity. At the highest - point, the speed is 0. Location F is higher than B and I. Speed is greatest at lower positions closer to the launch point and decreases as the ball goes up. So, the speed at I is greatest, followed by B, and then F is the smallest.

Step2: Understand acceleration 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 ($g\approx9.8\ m/s^{2}$) throughout the motion, regardless of its position. So, the acceleration at B, F, and I is the same.

Answer:

Ball Speed - Magnitude Only:
Smallest: F
Middle: B
Greatest: I
