In a one dimensional elastic collision of two bodies of same masses, what will happen if the moving body collides with the mass which is initially at rest?
Correct answer: A. Their velocities will be interchanged
- A. Their velocities will be interchanged
- B. Velocities of both bodies will be zero
- C. Moving body will continue its motion
- D. Moving body will come at rest and the mass at rest will start its motion
Explanation
The following is the solution: In a one-dimensional elastic collision of two bodies of equal mass, the velocities of the two bodies will be interchanged. This is because the kinetic energy of the system is conserved in an elastic collision.

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.
