Answer:
D.
Step-by-step explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;

Where;
- K.E represents kinetic energy measured in Joules.
- M represents mass measured in kilograms.
- V represents velocity measured in metres per seconds square.
Generally, when the final velocity at which a physical object moves is equal to zero (0), then it possess maximum kinetic energy.
Hence, the letter which shows the ball when it has the maximum kinetic energy in the graph attached is D.
