A1 kg freight car is rolling along a track at 3 m/s. calculate the time needed for a 1000 n force to stop it.

Car will take 1.5 sec to stop

Explanation:

We have given mass of the car m = 10000 kg

Force needed to stop the car F = 1000 N

According to newton's law

As the car stops finally so final velocity v = 0 m/sec

Initial velocity u = 3 m/sec

According to first equation of motion

t = 1.5 sec

true

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.
