A o.5 kg mass is launched horizontally across a smooth table. It is launched from a spring of constant. k = 450N/m that is compressef 10 cm. the mass then collides and sticks to another block of mass 1 kg 1. what is the speed of the first mass as leaves the spring. b. what is the speed of both blocks immediately ​

  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.
