**Problem 3: Energy Transformation Scenario**

Suppose an object at a given location has a potential energy of \( U_i = 10 \, \text{J} \) and a kinetic energy of \( K_i = 20 \, \text{J} \). Assuming there are no other outside forces acting on the object, how much kinetic energy does the object have when its potential energy is \( U_f = 40 \, \text{J} \)?

Options:
- (a) \( K_f = -10 \, \text{J} \)
- (b) \( K_f = 20 \, \text{J} \)
- (c) \( K_f = 50 \, \text{J} \)
- (d) This situation cannot be achieved.
