If two cars are moving with velocity 10 m/s and 5m/s in opposite direction to each other, then their relative velocity with respect to one another will be:
Correct answer: D. 15m/s
- A. 5m/s
- B. 10m/s
- C. -5m/s
- D. 15m/s
Explanation
The relative velocity of the two cars with respect to one another can be found by adding their velocities. Since they are moving in opposite directions, we need to subtract the velocity of one car from the other: Relative velocity = velocity of first car - velocity of second car = 10 m/s - (-5m/s) = 10 m/s + 5 m/s = 15 m/s
