Suppose, a ball of mass M is thrown upwards from a point A and it reaches up to the highest point B and returns back to point A, which one among the following is correct ?

  1. A. Kinetic Energy at A = Potential Energy at B ✓
  2. B. Kinetic Energy at A = Potential Energy at A
  3. C. Kinetic Energy at B = Potential Energy at B
  4. D. Kinetic Energy at B = Kinetic Energy at A

Correct Answer: A. Kinetic Energy at A = Potential Energy at B

Explanation

By the principle of conservation of mechanical energy, the maximum kinetic energy at the point of release (A) is equal to the maximum potential energy at the highest point (B).
