Spaceship 1 and Spaceship 2 have equal masses of 150 kg. Spaceship 1 has an initial momentum magnitude of 900 kg-m/s. What is its initial speed? A. 9 m/s
B. 60 m/s
C. 90 m/s
D. 6 m/s​

  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.
