The population P of a certain country (in thousands) from 1999 through 2009 can be modeled by P(t) = −8.81t2 + 218.7t + 88,369, 9 ≤ t ≤ 19
where t is the year, with t = 9 corresponding to 1999

a- Potential

b- Kinetic

c- Kinetic  

d- Kinetic

e- Kinetic

f- Potential

Step-by-step explanation:

Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion.

Hence potential energy will the body possess, if it is at rest otherwise if it is in motion, kinetic energy would be there

Hence we find from the picture at point A and F the ball is not in motion hence at those points potential energy would be there

AT other points,namely B, C, D, E we see that the body is in motion.

Hence the kind of energy the body has will be kinetic energy
