Three blocks of masses $M_{1} = 10$ kg, $M_{2} = 20$ kg and $M_{3} = 30$ kg are connected in a row by light strings on a horizontal frictionless table. The system is pulled to the right with a force of 60 N applied at the $M_{3}$ end. Find the tension $T_{2}$ (in N) in the string between $M_{2}$ and $M_{3}$ .

Answer:

Solution:

Common acceleration: $a = \frac{60}{10 + 20 + 30} = 1$ m/s $^{2}$

$T_{2}$ pulls $M_{3}$ alone: $T_{2} = M_{3} a = 30 \times 1 = 30$ N
