Which letter shows the ball when it has maximum kinetic energy

5. The letter on the diagram below where the kinetic energy of the cannon ball is the greatest is at both A and E. Letter A is an example of the maximum kinetic energy as that is where the cannon has just shot the cannon ball, and letter E also is an example of maximum kinetic energy because that is the spot where the cannon ball has reached its maximum speed during free fall.

Answer:

1. Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
2. The answer is position B, because it is at its lowest point. Potential Energy is “stored energy.” It is energy that is ready to be converted or released as another type of energy.
3. Point A is a point of maximum potential energy and minimum kinetic energy. Point C is the point of maximum kinetic energy and minimum potential energy.
4. At an object's lowest point, kinetic energy is zero/ maximum while potential energy is zero / maximum.
5. So, the maximum of potential energy P is given when the kinetic energy K is zero (i.e. when v=0, in the turning points of the particle). In that case E=Pmax.
