the train took 80s to reduce its speed from 84m/s to 42m/s . explain why with the same braking force the train takes more than 80s to reduce its reduce its speed its speed from 42m/s to zero

number of electrons for neutral cl

  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.
