Object A has 27 J of kinetic energy. Object B has one-quarter the mass of object A. *By what factor does the speed of each object change if total work -18 J is done on each?

the final speed of object A changed by a factor of   = 0.58

the final speed of object B changed by a factor of = 1.29

Explanation:

Given;

kinetic energy of object A, = 27 J

let the mass of object A =

then, the mass of object B =

work done on object A = -18 J

work done on object B = -18 J

let be the initial speed

let be the final speed

For object A;

Thus, the final speed of object A changed by a factor of   = 0.58

To obtain the change in the final speed of object B, apply the following equations.

Thus, the final speed of object B changed by a factor of = 1.29

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
