6. A 15.5 kg rock falls from a cliff at a height of 138 m to a cliff that is 79 m above the ground. How fest the rock falling when it strikes the lower cliff?

your answer would be fusion

  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.
