Questions & Step-by-Step Solutions
A cyclist is moving at 15 m/s and a pedestrian is walking at 5 m/s in the same direction. What is the speed of the cyclist relative to the pedestrian?
Step 1: Identify the speed of the cyclist, which is 15 m/s.
Step 2: Identify the speed of the pedestrian, which is 5 m/s.
Step 3: Since both are moving in the same direction, to find the relative speed, subtract the speed of the pedestrian from the speed of the cyclist.
Step 4: Perform the subtraction: 15 m/s (cyclist) - 5 m/s (pedestrian) = 10 m/s.
Step 5: The result, 10 m/s, is the speed of the cyclist relative to the pedestrian.
Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by subtracting their speeds when they are moving in the same direction.
