Question

What can you say about the kinetic energy when both have the same mass?
A) 2 m/s
B) 4 over 2 m/s

  1. K E subscript A space equals space K E subscript B
  2. K E subscript A space greater than K E subscript B
  3. K E subscript A less than K E subscript B
  4. KEA ≥ KEB

hintHint:

KEA=KEB

The correct answer is: K E subscript A space equals space K E subscript B


    Kinetic energy is directly proportional to the square of its velocity. Here, both A and B has the same velocity hence, they have the same kinetic energy.
