Answer
(a) Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed
(b) A river flowing at a certain speed comprises kinetic energy as water has a certain velocity and mass.
