Question: Two observers are moving towards each other at speeds of 20 m/s and 30 m/s. What is the speed of one observer as seen by the other?

Options:

  1. 10 m/s
  2. 20 m/s
  3. 50 m/s
  4. 60 m/s

Correct Answer: 50 m/s

Solution: 

Relative speed = Speed of observer 1 + Speed of observer 2 = 20 m/s + 30 m/s = 50 m/s.

Two observers are moving towards each other at speeds of 20 m/s and 30 m/s. What

Questions & Step-by-Step Solutions

Two observers are moving towards each other at speeds of 20 m/s and 30 m/s. What is the speed of one observer as seen by the other?
Correct Answer: 50 m/s
  • Step 1: Identify the speeds of the two observers. Observer 1 is moving at 20 m/s and Observer 2 is moving at 30 m/s.
  • Step 2: Understand that when two objects are moving towards each other, their speeds add up to find the relative speed.
  • Step 3: Add the speed of Observer 1 (20 m/s) to the speed of Observer 2 (30 m/s).
  • Step 4: Calculate the total: 20 m/s + 30 m/s = 50 m/s.
  • Step 5: Conclude that the speed of one observer as seen by the other is 50 m/s.
  • Relative Velocity – The concept of relative velocity involves calculating the speed of one object as observed from another moving object, taking into account their respective speeds and directions.
