A man is walking with `3 m//s,` due east. Rain is falling vetically downwards with speed `4 m//s.` Find the direction in which man should hold his umbrella, so that rain does not wet him.

A

`37^(@)`

B

`53^(@)`

C

`tan^(-1)(3/5)`

D

`tan^(-1)(5/3)`

Text Solution

Verified by Experts

The correct Answer is:
a

`overset(rarr)V_(RG)=overset(rarr)V_(RM)+ overset(rarr)V_(MG)`
`tan theta =3/4`

A man is walking on a level road at a speed of 3.0 km/h. Rain drops fall vertically wth a sped of 4.0 km/h. Find the velocity of the raindrops with respect to the man.

By the term velocity of rain, we mean velocity with which raindrops fall relative to the ground. In absence of wind, raindrops fall vertically and in presence of wind raindrops fall obliqucly. Moreover raindrops acquire a constant terminal velocity due air resistance very quickly as they fall toward the carth. A moving man relative to himself observes an altered velocity of raindrops. Which is known as velocity of rain relative to the man. It is given by the following equation. vec(v)_(rm)=vec(v)_(r)-vec(v)_(m) A standstill man relative to himself observes rain falling with velocity, which is equal to velocity of the raindrops relative to the ground. To protect himself a man should his umbrella against velocity of raindrops relative to himself as shown in the following figure. Rain is falling vertically with velocity 80 cm/s. (a) How should you hold your umbrella ? (b) You start walking towards the east with velocity 60 cm/s. How should you hold umbrella ? (c) You are walking towards the west with velocity 60 cm/s.

How should you hold your umbrella ?
