Work , power & Energy Question will mark the brainiest If the average frictional forces are 4N, work out how much work the ball does against friction.
mass of ball = 3.5kg slope = 40 degrees to the horizontal base length = 4.8m GPE lost = 140J

  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.
