Expert Answer

(a) resultant velocity when both train and the person travels westward

Let west be the positive x-direction and north be the positive y-direction.

Physics homework question answer, step 1, image 1

Thus, the speed is 22.9 km/hr towards west and hence the compass points at 270°.

(b) resultant velocity when both train travels westward and the person travels eastward

Physics homework question answer, step 2, image 1

Thus, the speed is 15.7 km/hr towards west and hence the compass points at 270°.

(b) resultant velocity when both train travels westward and the person travels north

Physics homework question answer, step 3, image 1
