Physic problem a fuel tank explodes, ripping the container into two pieces of masses 11 kg and 15 kg and sending them 12.0 m and 11.0 m high, respectively. what was the energy released by the explosion if all energy becomes the ke of the fragments?

Explanation:

As the explosion occurs there is no external force on them

So here we can say that total momentum must be conserved

So we will have

in vertical direction the two parts will reach to maximum height of 12 m and 11 m respectively

So their speeds are given as

now we have

Energy of explosion = kinetic energy of both parts after explosion

So we will have

you would expect a sound wave to speed up. - b)
