Questions & Step-by-Step Solutions
A plane is flying at 200 m/s in still air. If there is a headwind of 50 m/s, what is the speed of the plane relative to the ground?
Correct Answer: 150 m/s
Step 1: Identify the speed of the plane in still air, which is 200 m/s.
Step 2: Identify the speed of the headwind, which is 50 m/s.
Step 3: Understand that a headwind slows the plane down relative to the ground.
Step 4: To find the speed of the plane relative to the ground, subtract the speed of the wind from the speed of the plane.
Step 5: Perform the calculation: 200 m/s (speed of plane) - 50 m/s (headwind) = 150 m/s.
Step 6: Conclude that the speed of the plane relative to the ground is 150 m/s.
Relative Speed – Understanding how to calculate the speed of an object in relation to another moving object, taking into account the direction of both.
