Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

**Problem Statement:**

A 2-lb ball \( B \) is traveling around in a horizontal circle of radius \( r_1 = 5.8 \, \text{ft} \) with a speed of \( (v_B)_1 = 3.4 \, \text{ft/s} \). If the attached cord is pulled down through the hole with a constant speed \( v_r = 1.1 \, \text{ft/s} \), determine how much time is required for the ball to reach a speed of 14 ft/s. Please pay attention: *the numbers may change since they are randomized*. Your answer must include 2 places after the decimal point, and proper unit.

**Diagram Explanation:**

The diagram shows a horizontal circular path with a blue ball labeled \( B \) moving in a circular motion. The radius of the circle is marked as \( r_1 \), and the initial velocity of the ball is \( (v_B)_1 \). There is a cord attached to the ball, which is being pulled down through a hole at a speed \( v_r \), illustrating the radial inward movement.
