Given: each block has masses m1 = m2 = m3 = m and the coefficient of kinetic friction is µ. the magnitude of f equals twice the total frictional force. apply a horizontal force f in pushing an array of three identical blocks in the horizontal plane (see sketch). m1 m2 m3 f µ find the force f23 with which the second block is pushing the third block.

  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.
