Motion In A Plane

Question
CBSEENPH11018456
Wired Faculty App

A girl walks 100 m at angle of 30° North of West. What is the ratio of the distance travelled by the girl in North to West direction?

Solution
Total distance covered by the girl is equal to total displacement = 100m
Angle, straight theta = 30o
Magnitude of the component of displacement along North is, straight S subscript 1 equals 100 space sin 30 degree
Magnitude of the component of displacement along West is,space straight S subscript 2 equals 100 space cos space 30 degree
Therefore, the ratio of the distance travelled by the girl in North to West direction is given by,
