Question

a group of physics students are investigating free - fall. three balls are dropped. which of the following rankings correctly describes the order in which the objects reach the ground? a all of the balls will reach the ground at different times because mass and diameter affect free - fall acceleration. b ball 2 and ball 3 reach the ground before ball 1 because they have a larger mass. ball diameter of ball mass 1 24.25 cm 0.6 kg 2 24.25 cm 8.0 kg 3 12.00 cm 8.0 kg

Explanation:

Step1: Recall free - fall principle

In the absence of air resistance, all objects in free - fall near the Earth's surface have the same acceleration \(g\approx9.8\ m/s^{2}\), regardless of their mass or diameter.

Step2: Analyze the situation

Since the balls are in free - fall and air resistance is not considered, they will all reach the ground at the same time.

Answer:

None of the given options (as all balls will reach the ground at the same time in the absence of air - resistance).
