An inclined plane at of angle 15° is used to raise a load of 4500N through a height of 2m. If the plane is 75% efficient, calculate: 1)The velocity ratio of the plane
2)work done on the load

  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.
