# Shown above are three masses of \(6 \, \text{kg}\), \(3 \, \text{kg}\), and \(1 \, \text{kg}\) (in order from left to right). You pull on the first mass with a force of \(15 \, \text{N}\) along a frictionless surface.

Shown above are three masses of \(6 \, \text{kg}\), \(3 \, \text{kg}\), and \(1 \, \text{kg}\) (in order from left to right). You pull on the 1kg mass with a force \(F\) of \(15 \, \text{N}\) along a frictionless surface.

**Part a)** Find the acceleration of the system. *(3 points)*

**Part b)** Find the tension \(T_1\) of the string between the \(6 \, \text{kg}\) mass and the \(3 \, \text{kg}\) mass. *(3 points)*

**Part c)** Find the tension \(T_2\) of the string between the \(3 \, \text{kg}\) mass and the \(1 \, \text{kg}\) mass. *(3 points)*
