5. Calculate the speed of a 5 kg object that possesses 260 J of kinetic energy. 6. Calculate the potential energy of a 7 kg object positioned 50 m above the ground.
7. Calculate the height of a 10 kg object that has 780 J of potential

  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.
