STANDARD Physics Average Speed MCQ Question
A body moving along a straight line travels one third of the total distance with a speed of 3.0 m s⁻¹. The remaining distance is covered with a speed of 4.0 m s⁻¹ for half the time and 5.0 m s⁻¹ for the other half of the time. The average speed during the motion is
4.0 m s⁻¹
6.0 m s⁻¹
3.8 m s⁻¹
2.4 m s⁻¹
Correct Answer
Detailed Explanation
The average speed is calculated by dividing the total distance by the total time. The given speeds and distances allow us to calculate the average speed as 3.8 m s⁻¹.
