Three blocks of masses \(1.0\,\text{kg}\), \(2.0\,\text{kg}\), and \(4.0\,\text{kg}\) are connected by massless strings, one of which passes over a frictionless pulley of negligible mass, as shown above. Calculate each of the following.(a) The acceleration of the \(4\)-kilogram block. Solve as a system. , (b) The tension in the string supporting the \(4\)-kilogram block. , (c) The tension in the string connected to the l-kilogram block. :

\(\approx 1.4\, \text{m/s}^2 \) \( T_4 = 33.6 \, \text{N} \) \( T_1 = 11.2 \, \text{N} \)
