Answer:
[tex]-70\hat{i} m+19\hat{j}m+21\hat{k} m[/tex]
Explanation:
We are given that
Displacement along x- axis =-[tex]70\hat{i}[/tex] m
Displacement along y-axis=[tex]19\hat{j}[/tex]m
Displacement along z-axis=[tex]21\hat{k} m[/tex]
Where [tex]\hat{i},\hat{j},\hat{k}[/tex] are unit vector along x, y and z-axis
We have to find the displacement from start to end in unit vector notation.
Total displacement from start to end=Displacement along x-axis+displacement along y-axis+displacement along z- axis
Total displacement from start to end=[tex]-70\hat{i} m+19\hat{j}m+21\hat{k} m[/tex]
Hence, the displacement of the sign from start to end=[tex]-70\hat{i} m+19\hat{j}m+21\hat{k} m[/tex]
