Momentum

In summary, momentum is a measure of an object's motion, taking into account its mass and velocity. In an explosion, the total momentum of the system before and after the explosion remains the same, following the law of conservation of momentum. The mass of the two pieces will determine the distribution of momentum after the explosion, with the larger piece having greater momentum. The velocity of the two pieces will also change after an explosion, as the momentum is distributed differently between them. The force of an explosion is related to momentum through the equation F=ma, with the force being the result of the rapid acceleration caused by the sudden release of energy.

A 12 kg mass is initially moving due east at 6 m/s on a frictionless surface. It suddenly explodes into two pieces, both of which move along an east/west line. If one fragment of 8 km is moving at 18 m/s east after the collision, find the velocity of the other fragment.

Welcome to forum.So how did you attempt the problem.

1. What is momentum?

Momentum is a measure of an object's motion, taking into account its mass and velocity. It is the product of an object's mass and velocity.

2. How is momentum conserved in an explosion?

In an explosion where an object breaks into two pieces, the total momentum of the system before and after the explosion will remain the same. This is known as the law of conservation of momentum.

3. How does the mass of the two pieces affect the momentum after an explosion?

The mass of the two pieces will determine the distribution of momentum after the explosion. The larger the mass of one piece, the greater its momentum will be compared to the other piece.

4. Does the velocity of the two pieces change after an explosion?

Yes, the velocity of the two pieces will change after an explosion. This is because the momentum of the system remains constant, but it is distributed differently between the two pieces.

5. How is momentum related to the force of an explosion?

Momentum and force are related through the equation F=ma, where F is the force, m is the mass, and a is the acceleration. In an explosion, the force is the result of the rapid acceleration of the two pieces, which is caused by the sudden release of energy.
