A particle of m mass moving at a v speed collides with a stationary particle of another m mass. What will be the velocity of the first particle after the collision?

A particle of m mass moving at a v speed collides with a stationary particle of another m mass. What will be the velocity of the first particle after the collision? Correct Answer Zero

The correct answer is Zero.

  • This concept is known as the Conservation of linear momentum.
  • In this, the total momentum of the system will always remain constant.
  • The first particle of mass m collides with another particle of the same mass, then the momentum of the first transferred to the second, and the momentum (which equals zero) is transferred to the first.
  • Therefore, the velocity of the first is equaled to zero.
  • This concept is explained in Newton's Third law of motion.

Additional Information

Newton First law of the Motion An object will not change its motion unless an external or internal force acts on it.
Newton Second law of the Motion The force on an object is equal to its mass times its acceleration.
Newton Third law of the Motion When two objects interact, they apply forces to each other of equal magnitude and opposite direction.

How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
