MCQ

Wind is blowing in the north direction at speed of $2 \,\,m/s$ which causes the rain to fall at some angle with the vertical. With what velocity should a cyclist drive so that the rain appears vertical to him :

A
$2\,\, m/s$ south
✓
$2\,\, m/s$ north
C
$4 \,\,m/s$ west
D
$4 \,\,m/s$ south

✓

Answer

Correct option: B.

$2\,\, m/s$ north

b
Horizontal component of rain's velocity will be equal to velocity of wind which is $2 m / s$ in north direction. If cyclist goes towards north with velocity $2 m / s,$ then $w.r.t$ him rain's horizontal component of velocity will be zero, and he will see only vertical component.
