2m/min

3m/min

8m/min

10m/min

Answer 1

Answer:

The slope of a Speed-time graph shows the acceleration of the car. A steep slope indicates rapid acceleration. By calculating the gradient of the slope the acceleration can be obtained

Acceleration==

run

rise

=

time

initialvelocity−finalvelocity

So region BC gives the acceleration.

And a downward slope of a speed-time graph shows the deceleration of the car.
