5. Suppose an object at a given location has potential energy of Ui = 10 J and kinetic energy of Ki= 20 J. Assuming there are no othe outside forces acting on the object, how much potential energy does the object have when its kinetic energy is Kf= 15 J. (a) Uf= 5 J (b) Uf = 10 J (c) Uf = 15 J (d) This situation cannot be achieved.

Expert Solution
Step 1
The total energy of any object is given as the sum of its potential and kinetic energy.
So,
In a conservative system, where there are no non-conservative forces acting on the object, the total energy of the system remains conserved, according to the law of conservation of energy.
This means the initial energy of an object at some instant should equal the final energy of the object at some other instant
In the given problem, the given object has an initial potential energy of 10 J, and an initial kinetic energy of 20 J.
Thus, the total energy of the object is
