Question

Rain is falling vertically with a speed of 35m/s. A woman rides a bicycle with a speed of 12m/s in east to west direction. What is the relative velocity and direction in which she should hold her umbrella?

Answer 1

hii
here's your answer
....
Vrel =√(v²rain+v²of man)
=√(35²+12²)
= √(1369)
=37m/s
and direction will be
tan theta = 12/35
=>theta = tan-¹(12/35)
