6. part a please

**Force and Motion Problem**

A force of 10 lb is applied to the cord. Block \( A \) weighs 24 lb. Neglect the mass of the pulleys and cords. (Figure 1)

**Part A**

Determine the time needed to pull the cord at \( B \) down 8 ft starting from rest.

Express your answer to three significant figures and include the appropriate units.

\[
t = \, \_\_\_\_\_\_ \, 
\]

Input: `.305 \ S`

**Diagram Explanation**

The figure depicts a pulley system with two pulleys and a cord. Block \( A \), weighing 24 lb, is suspended. A force of 10 lb is applied downward on the cord at point \( B \). This setup illustrates the dynamics of forces and motion in a mechanical system.
