Question

The three balls in FIGURE $Q10.4$, which have equal masses, are fired with equal speeds from the same height above the ground. Rank in order, from largest to smallest, their speeds v_a, v_b, and v_c as they hit the ground. Explain.

Short answer

All of the speeds as they reach the ground are the same.

Step-by-step solution

Content Introduction

Kinetic energy is a type of energy that may be exchanged between objects and converted into other forms of energy. The quantity of kinetic energy that an object has is determined by two variables: the object's mass (m) and its speed (v).

Content Explanation

Three balls with equal masses will hit the ground at the same speed because they have the same starting Kinetic Energy, and the direction of speed (v0) won't change that.
