When two bodies move toward each other at constant speeds, the distance between them decreases at the rate of 6m/sec. If they move in the same. direction, the distance between them increases at the rate of 4M/sec. Then their speeds are:
Correct answer: A. 5m/s, 1m/s
- A. 5m/s, 1m/s
- B. 3m/s, 3m/s
- C. 6m/s, 1m/s
- D. 4m/s, 2m/s
Explanation
Given:- When moving toward each other, the distance between them decreases at 6 m/s.- When moving in the same direction, the distance between them increases at 4 m/s.Let the speeds of the two bodies be V1 m/s and V2 m/s.Motion Toward Each Other:The relative speed when moving toward each other is the sum of their speeds: V1 + V2 = 6 m/s.Motion in the Same Direction:The relative speed when moving in the same direction is the difference of their speeds: V1 - V2 = 4 m/s.Calculating Speeds:Solving the equations:- Adding the two equations gives: 2V1 = 10 , so V1 = 5 m/s.- Substituting V1 = 5 m/s into one of the equations gives: 5 + V2 = 6, so V2 = 1 m/s.The calculated speeds of the two bodies are 5 m/s and 1 m/s, satisfying both conditions provided in the question.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
