When a person moves towards a mirror with velocity 3v, by which velocity his image moves relative to himself ?

Text Solution

AI Generated Solution

To solve the problem of finding the velocity of the image relative to the person moving towards the mirror, we can follow these steps: ### Step 1: Understand the scenario A person is moving towards a mirror with a velocity of \(3v\). When a person moves towards a mirror, their image also moves towards them, but at a different rate. ### Step 2: Determine the velocity of the image When the person moves towards the mirror with a velocity of \(3v\), the image of the person in the mirror will also move towards the person at the same speed \(3v\). This is because the image in a plane mirror is always at the same distance behind the mirror as the person is in front of it. ...

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.
