____ [38]

Answer:190.78 km

Explanation:

Given

First Displacement is 100 km ^{\circ}west of north

Position Vector (r_1)of displacement is given by

\vec{r_1}=100cos10\hat{j}-100sin10\hat{i}

\vec{r_1}=98.48\hat{j}-17.36\hat{i}

Considering East as X axis and North Y axis

second displacement is 120 km 50^{\circ} east of north

Now position Vector of second Position w.r.t to first

\vec{r_{21}}=120cos50\hat{j}+120sin50\hat{i}

\vec{r_{21}}=77.13\hat{j}+91.92\hat{i}

\vec{r_2}=\vec{r_1}+\vec{r_{21}}

\vec{r_2}=98.48\hat{j}-17.36\hat{i}+77.13\hat{j}+91.92\hat{i}

\vec{r_2}=74.56\hat{i}+175.61\hat{j}

magnitude of displacement

|r_2|=190.78 km
