A man rows a boat with a speed of 18 km/hr in north-west direction. The shore line makes an angle of 15° south of west. Obtain the components of velocity of boat along shore line and perpendicular to shore line.

The velocity of boat is 18 km/hr in N-W direction and shore line makes angle 15° with S of W.

Therefore the velocity vector of boat subtends an angle of 60° with shore line.

Component of velocity of boat
along shore line =

And component of velocity of boat perpendicular to shore line
