### Educational Content: Physics Problem Involving Friction and Motion#### DescriptionA hand applies a constant force \( N_{\text{hand,A}} = 75 \, \text{N} \) to a block labeled as Block A (\( m_A = 3 \, \text{kg} \)). The block is pushed over a \( 2 \, \text{m} \) distance along a table that is primarily frictionless. Block A accelerates from rest and achieves a speed of \( 8 \, \text{m/s} \) upon passing over a rough section of the table with a coefficient of kinetic friction \( \mu_k = 0.4 \). After crossing this section, Block A collides with a larger block, Block B (\( m_B = 6 \, \text{kg} \)), which is initially at rest.#### TaskCalculate \( \Delta x \), the length of the rough section of the table, using the provided information.#### OptionsA) \( 1.0 \, \text{m} \) B) \( 15.4 \, \text{m} \) C) \( 4.5 \, \text{m} \) D) \( 7.5 \, \text{m} \) E) \( 2.6 \, \text{m} \)#### Diagram ExplanationThe diagram illustrates the scenario:- Two hands pushing Block A across a surface.- Block A is moving to the right with a velocity \( v_A = 8 \, \text{m/s} \) after crossing the rough section.- The rough section is marked with hatching to denote friction (\( \mu_k = 0.4 \)).- Block B is stationary at the end of the rough section, ready to be impacted by Block A.Please select the correct length for the rough section of the table from the given options.

A hand pushes block A (m= 3 kg) with a constant force Nand. A= 75 N for a distance Ax = 2 m along a (mostly) frictionless table such that it speeds up from rest and is traveling at a speed of 8 m/s after it slides over a rough section of the table (H = 0.4). Block A then collides with a more massive block B (mg = 6 kg) that is initially at rest. Find Ax, the length of the rough section of the table. A) 1.0 m B) 15.4 m C) 4.5 m D) 7.5 m E) 2.6 m
