Question

Rain is falling vertically with a speed of 123 m/s. A woman rides a bicycle with a speed of 12 m/s from East to West direction. What is the velocity of rain relative to the woman?
(Take east and vertically upward as positive x-axis and positive y-axis respectively.)

Solution

The correct option is C (12^i123^j) m/s
Let West to East direction be positive x – axis and upward direction be positive y – axis.
Therefore, Velocity of rain fall w.r.t ground vR=12(3)^j m/s
Velocity of woman w.r.t. ground vw=12^i m/s
Hence, velocity of rain w.r.t woman = vrw=vrvw=123^j(12^i) m/s=12^i123^j m/s
