Internal explosion, kinetic energy prob

In summary, an internal explosion with a release of 7500 J of energy breaks an object into two pieces, one with 1.5 times the mass of the other. Using the equation for linear momentum conservation, the kinetic energy acquired by each piece can be calculated as p^2/2m. However, it is not clear how to incorporate this information with the given values.

Homework Statement


an internal explosion breaks an object, initially at rest, into two pieces, one of which has 1.5 times the mass of the other. If 7500 J were released in the explosion, how much kinetic energy did each piece acquire.


Homework Equations


mgyi+1/2mvi2=mgyf+1/2mvf2

You don't need that (mgy). Energy released in the explosion will go into kinetic energy of two pieces. And will linear momentum be conserved in this case? if so, use this fact.

ok well understand that m1v+m2v=m1vf+m2
and KE=p2/2m ... but i just can't figure out how to put this together with the information that I am given.
 

FAQ: Internal explosion, kinetic energy prob

What is an internal explosion?

An internal explosion is a type of explosion that occurs within a closed container or structure, rather than in an open environment. This can cause a build-up of pressure and release of energy that can result in damage or destruction of the container.

How is kinetic energy involved in an internal explosion?

Kinetic energy is involved in an internal explosion because it is the energy of motion. When the explosion occurs, the molecules of the explosive material gain kinetic energy and move rapidly, causing the container to rupture. This release of kinetic energy is what causes the damage.

What factors affect the kinetic energy in an internal explosion?

There are several factors that can affect the kinetic energy in an internal explosion, including the amount and type of explosive material, the size and shape of the container, and the surrounding environment. The type of explosion, such as a chemical or nuclear explosion, can also play a role in the amount of kinetic energy released.

How is the amount of kinetic energy in an internal explosion calculated?

The amount of kinetic energy in an internal explosion can be calculated using the formula KE = 1/2mv^2, where m is the mass of the explosive material and v is the velocity of the explosion. However, this calculation may not always accurately reflect the actual energy released due to other factors involved in the explosion.

What safety precautions should be taken to prevent internal explosions?

To prevent internal explosions, it is important to handle explosive materials properly and follow all safety protocols. This includes proper storage, handling, and disposal of explosive materials, as well as regular maintenance and inspection of containers and structures. It is also important to be aware of potential hazards and follow safety guidelines when working with explosive materials.
