Explanation Given data: Refer to the Figure P5.82 in the textbook for the connection of two blocks by a string. Coefficient of kinetic friction between the block and the table ( μ k ) is 0.20. Formula used: Write the expression for equilibrium equation of force for the x -component as follows. ∑ F x = 0 (1) Here, ∑ F x is the sum of the forces in the x -component. Write the expression for equilibrium equation of force for the y -component as follows. ∑ F y = 0 (2) Here, ∑ F y is the sum of the forces in the y -component. Write the expression for normal force as follows. n = m g (3) Here, m is the mass of the block, and g is the acceleration due to gravity, which is 9.8 m s 2 . Explanation: Consider the pulley is massless and frictionless. Consider the block of 1.0 kg as m 1 , and the block of 2.0 kg as m 2 . From the given data, the x -component of the forces on the block m 2 , and y -component of the forces on the block m 1 . From the given data, modify the expression in equation (1) for equilibrium equation for the forces in the horizontal line ( x -component) as follows. T − μ k n 2 = m 2 ( a x ) 2 (4) Here, T is the tension in the string, μ k is the coefficient of kinetic friction between the block and the table, which is 0.20, n 2 is the normal force on block m 2 , and ( a x ) 2 is the acceleration of the block m 2 . From the given data, modify the expression in equation (2) for equilibrium equation for the forces in the vertical line as follows. T − n 1 = m 1 ( a y ) 1 (5) Here, n 1 is the normal force on block m 1 , and ( a y ) 1 is the acceleration of the block m 1 . Rewrite the expression in equation (5) for the tension in the string as follows. T = n 1 + m 1 ( a y ) 1 Substitute [ n 1 + m 1 ( a y ) 1 ] for T in equation (4), [ n 1 + m 1 ( a y ) 1 ] − μ k n 2 = m 2 ( a x ) 2 From equation (3), substitute m 1 g for n 1 , and m 2 g for n 2 . [ m 1 g + m 1 ( a y ) 1 ] − μ k m 2 g = m 2 ( a x ) 2 (6) From the given data, consider acceleration as follows
