Q. A moving body collides with a stationary body of equal mass in a perfectly elastic head-on collision. The result is

एक गतिमान पिंड समान द्रव्यमान के एक स्थिर पिंड से बिल्कुल लोचदार आमने-सामने की टक्कर में टकराता है। परिणाम है

A
First stops, second moves
पहला रुकता है, दूसरा चलता है
B
Both move together
दोनों एक साथ चलते हैं
C
First reverses
पहला उलटा
D
Second remains stationary
दूसरा स्थिर रहता है

Explanation

In a perfectly elastic head-on collision between equal masses, the moving object transfers its velocity to the stationary object. So:

  • The first body comes to rest.

  • The second body moves with the initial velocity of the first.
