A student is pushing a 35 kg desk across a floor at a constant speed of 4 m/s. How much work, to the nearest whole joule, must the student do on the desk to change the speed to
6 m/s?

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

  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.
