$53.6\,i+53.6\,j$

Explanation:

The mathematical notation for the displacement vector R is given by

$R \,\cos \theta \,i+R \,\sin\theta\,j$

Now a bird flies straight northeast a distance of 75.8 km for 3.5 h such that x-axis points towards east and the y-axis points towards north.

Put R=75.8 and $\theta =45$ $75.8 \,\cos 45\° \,i+75.8 \,\sin45\°\,j=\frac{75.8}{\sqrt{2} } i+\frac{75.8}{\sqrt{2} } j=53.6\,i+53.6\,j$

Therefore,

Displacement vector is given by
