Passage / Comprehension

A car travels south for 8 minutes with a speed of v = 60 kmph, then turns and begins to move in a direction 53° north of west and travels at the same speed for 10 minutes.

Find the total displacement of the car (both magnitude and direction).

Options:

Answer:

Solution:

$S_{1} = v_{1} t = 8000 m$

$S_{2} = v_{2} t = 10, 000 m$

$S = - 10000 cos 5 3^{\circ} \hat{i} + 10000 sin 5 3^{\circ} \hat{j} - 8000 \hat{j}$

$S = - 6000 \hat{i}$
