Suppose two objects collide head on, where initially object 1 (mass = m 1 ) is m

Question

Suppose two objects collide head on, where initially object 1 (mass = m1) is moving and object 2 (mass = m2) is stationary. Now assume that they have the same mass (m1 = m2). Which one of the following statements is true and give the reasoning.

A) Object 1 rebounds with one-half its initial speed, while object 2 moves to the right with one-half the speed that object 1 had before the collision.

B) Object 1 stops completely, while object 2 acquires the same velocity (magnitude and direction) that object 1 had before the collision.

Explanation / Answer

A) Object 1 rebounds with one-half its initial speed,

while object 2 moves to the right with one-half the speed that object 1 had before the collision.

is correct

because object 1 having initial speed and object 2 is at rest or stationary

and in the second option B) has given that object 1 completely stops,

this will not happen when object is collide because that will both travelling with a final speed.

and same velocity will not aquire final speed get reduce.
