Momentum:

$\overline{){\mathbf{p}}{\mathbf{=}}{\mathbf{m}}{\mathbf{v}}}$

**Part A**

The total momentum of the system is equal to the sum of momenta of the two particles.

The vector sum of the individual momenta of all objects constituting the system.

In this problem, you will analyze a system composed of two blocks, 1 and 2, of respective masses m_{1} and m_{2}. To simplify the analysis, we will make several assumptions: The blocks can move in only one dimension, namely, along the x axis. The masses of the blocks remain constant. The system is closed. At time t, the x components of the velocity and the acceleration of block 1 are denoted by v_{1}(t) and a_{1}(t). Similarly, the x components of the velocity and acceleration of block 2 are denoted by v_{2}(t) and a_{2}(t). In this problem, you will show that the total momentum of the system is not changed by the presence of internal forces.

Part A Find p(t), the x component of the total momentum of the system at time t. Express your answer in terms of m_{1}, m_{2}, v_{1}(t), and v_{2}(t). p(t) =

Part B Find the time derivative dp(t)/dt of the x component of the system's total momentum. Express your answer in terms of m_{1}, m_{2}, a_{1}(t), and a_{2}(t). dp(t)/dt =
