An 80.0 kg man playing hockey catches a puck moving at 20.0 m/s. the man is initially at rest. the man and puck move together after the collision. the puck's mass is 0.17 kg. what is the final velocity?

  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.
