Which equation correctly relates kinetic energy, mass, and velocity?

which of the following is an example of kinetic energy?
a boy resting on a park bench
a book sitting on a shelf
a rubber band stretched as far as it can go
a swing moving back and forth

if they have a finite resultant

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
