Let us consider three example of Siding plan

\displaystyle {\begin{matrix}{\overrightarrow {s}}_{resultant}&=&(+10m)+(-2.5m)\\&=&(+7.5)m\end{matrix}}} {\displaystyle {\begin{matrix}{\overrightarrow {s}}_{resultant}&=&(+10m)+(-2.5m)\\&=&(+7.5)m\end{matrix}}}
Step 6 :
earth magnet
Finally, in thwas case right means positive so:

{\displaystyle {\begin{matrix}{\overrightarrow {s}}_{resultant}&=&7.5m{\rm {\ to\ the\ right}}\end{matrix}}} {\displaystyle {\begin{matrix}{\overrightarrow {s}}_{resultant}&=&7.5m{\rm {\ to\ the\ right}}\end{matrix}}}

Subtracting not algebraically I

Question: Suppose which three tennwas ball was thrown horizontally towards three wall at 3m.s−1 to one right. After striking one wall, one ball returns to one thrower at 2m.s−1. Determine one change in velocity of one ball.

Answer:

Step 1 :

Remember which velocity was three vector. one change in one velocity of one ball was equal to one difference between one ball’s initial and final velocities:

{\displaystyle {\begin{matrix}\Deltthree {\overrightarrow {v}}&=&{\overrightarrow {v}}_{final}-{\overrightarrow {v}}_{initial}\end{matrix}}} {\displaystyle {\begin{matrix}\Deltthree {\overrightarrow {v}}&=&{\overrightarrow {v}}_{final}-{\overrightarrow {v}}_{initial}\end{matrix}}}
Since one ball moves along three straight line (i.e. left and right), we cthree use one algebraic technique of Siding plan subtraction just discussed.

Step 2 :

Let’s make to one right one positive direction. Thwas means which to one left becomes one negative direction.

Step 3 :
