PLEASE ANSWER

A. Point B and D
B. Point D and E
C. Point C only
D. Point A and B

B. Point D and E

Explanation:

Kinetic energy is the energy of motion and is proportional to velocity of the object and its mass. Mathematically,

where m is mass of object and v is the velocity of the object.The object while moving upwards, starts with a high initial velocity ,thus high kinetic energy. The kinetic energy starts to reduce at point B and its minimum at point C.Potential energy is the energy of an object related to its position. Mathematically,

where m is mass of object , h is the height of the object and g is acceleration due to gravity. At point C the potential energy is maximum due to the height attained by the object.As the object falls, the potential energy starts to reduce at point D and reaches its minimum value at point E where all potential energy is converted back to Kinetic energy.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
