Question

Overview of the Experimental Procedure In this experiment, you will graphically construct vectors to represent the velocity of each puck before and after the collision. The arrows you draw to represent these velocities will have to be labeled with descriptive notations such as $\vec{v_{1i}}$, $\vec{v_{1f}}$, $\vec{v_{2i}}$, and $\vec{v_{2f}}$ where subscript "i" (initially) stands for before the collision and subscript "f" (finally) stands for after the collision. To find the changes in velocity experienced by the pucks, $\Delta \vec{p_1} = \vec{p_{1f}} - \vec{p_{1i}}$ and $\Delta \vec{p_2} = \vec{p_{2f}} - \vec{p_{2i}}$, you will graphically subtract velocity vectors. Your comparison of puck 1's change in velocity with that of puck 2 will be a comparison of two arrows you have constructed. In comparing the arrows which represent $\Delta \vec{p_1}$ and $\Delta \vec{p_2}$, you will have to examine both their magnitudes and their directions.

          Overview of the Experimental Procedure
In this experiment, you will graphically construct vectors to represent the velocity of each puck before and
after the collision. The arrows you draw to represent these velocities will have to be labeled with
descriptive notations such as
$\vec{v_{1i}}$, $\vec{v_{1f}}$, $\vec{v_{2i}}$, and $\vec{v_{2f}}$
where subscript "i" (initially) stands for before the collision and subscript "f" (finally) stands for after the
collision.
To find the changes in velocity experienced by the pucks,
$\Delta \vec{p_1} = \vec{p_{1f}} - \vec{p_{1i}}$
and
$\Delta \vec{p_2} = \vec{p_{2f}} - \vec{p_{2i}}$,
you will graphically subtract velocity vectors.
Your comparison of puck 1's change in velocity with that of puck 2 will be a comparison of two arrows you
have constructed. In comparing the arrows which represent
$\Delta \vec{p_1}$ and $\Delta \vec{p_2}$, you will have to examine both their magnitudes and their directions.

Overview of the Experimental Procedure
In this experiment, you will graphically construct vectors to represent the velocity of each puck before and
after the collision. The arrows you draw to represent these velocities will have to be labeled with
descriptive notations such as
v⃗1⃗i⃗, v⃗1⃗f⃗, v⃗2⃗i⃗, and v⃗2⃗f⃗
where subscript "i" (initially) stands for before the collision and subscript "f" (finally) stands for after the
collision.
To find the changes in velocity experienced by the pucks,
Δp⃗1⃗ = p⃗1⃗f⃗ - p⃗1⃗i⃗
and
Δp⃗2⃗ = p⃗2⃗f⃗ - p⃗2⃗i⃗,
you will graphically subtract velocity vectors.
Your comparison of puck 1's change in velocity with that of puck 2 will be a comparison of two arrows you
have constructed. In comparing the arrows which represent
Δp⃗1⃗ and Δp⃗2⃗, you will have to examine both their magnitudes and their directions.
