A stone with a mass of 0.724 kg is dropped from the edge of a cliff. When the stone strikes the ground, the internal energy of the stone and ground increase by 2,307 J. If the stone is initially at rest when it is dropped, how high above the ground is the cliff? (g = 10 m/s2)

c

explanation:

  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.
