Questions & Step-by-Step Solutions
A cyclist is moving at 15 m/s towards the east while a car is moving at 25 m/s towards the west. What is the relative speed of the cyclist with respect to the car?
Correct Answer: 40 m/s
Step 1: Identify the speed of the cyclist, which is 15 m/s towards the east.
Step 2: Identify the speed of the car, which is 25 m/s towards the west.
Step 3: Understand that when two objects are moving towards each other, their relative speed is the sum of their speeds.
Step 4: Add the speed of the cyclist (15 m/s) to the speed of the car (25 m/s).
Step 5: Calculate the total: 15 m/s + 25 m/s = 40 m/s.
Step 6: Conclude that the relative speed of the cyclist with respect to the car is 40 m/s.
Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by adding their speeds when they are moving towards each other.
