A car is going at 11.2 m/s on a horizontal straight road. Whenthe traffic light is 30 m away, it turns red.
The reaction time of the driver is 0.3 s.
The car stops just before the traffic light with constantdeceleration when the break is applied.

  1. Find the time it takes for the car to stop, from the moment thelight becomes red.

  2. Plot speed of the car on y-axis and the time on the x-axis,taking t=0 at the

    moment when the traffic light turns red.

  3. In the table provided below fill-up the blanks. It will help youto plot the graphs.

  4. Plot the acceleration as a function of time.

  5. Plot the distance covered as a function of time, using the v vs.t graph, taking zero

    at t=0.

Time in s

Speed (m/s)

Acceleration (m/s2)

Distance covered (m)
