  • a)
    does not change
  • b)
    becomes twice to that of initial
  • c)
    becomes 4 times that of initial
  • d)
    becomes 16 times that of initial
Correct answer is option 'A'. Can you explain this answer?

Explanation:

Potential energy is the energy possessed by an object due to its position or configuration. In this case, the car is moving on a levelled road, indicating that there is no change in its height or position. Therefore, the potential energy of the car remains constant and does not change.

To summarize, the correct option is A) does not change.

Option 'a' is correct because
suppose a body of mass 'm' is moving with uniform velocity 'u' then let there be some external force displacing the body by 's' so as its final velocity becomes 'v'. in this condition the kinetic energy of moving body is equal to the work that was required to change its velocity.
the relation becomes
v^2=u^2+2as
