Wo bullets are fired at the same time with the same kinetic energy. if one bullet has twice the mass of the other, which has the greater speed and by what factor? which can do the most work? t

velocity of other bullet will be

As kinetic energy of both bullet are same so they will do same amount of work

Explanation:

We have given that two bullets are fired with same kinetic energy

So

Let the mass of bullet 1 is and mass of bullet 2 is

And their velocity are and

According to question

So

So velocity of other bullet will be

As kinetic energy of both bullet are same so they will do same amount of work

this could be newton#'s law of cooling. the cooling curve is exponential
