Mathematics · Motion in a Straight Line
A person travelling in a straight line moves with a constant velocity v1 for a certain distance 'x' and with a constant velocity v2 for the next equal distance. The average velocity v is given by the relation:
- 12v = 1v1 + 1v2✓
- 21v = 1v1 + 1v2
- 3v = √(v1v2)
- 4v2 = v1 + v22
Correct answer
2v = 1v1 + 1v2
