With an average acceleration of-1.2 m/s^2 how much time will it take a cyclist to bring a bicycle with an initial velocity of 6.5m/s to a complete stop

Average acceleration given initial and final velocities and , respectively, over a time interval lasting is

from which we find

To arrive at a complete stop, the cyclist's final velocity will be 0 m/s, so the time it takes to do so is

260 miles per hour

explanation:

  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.
