The diagram below shows the speed-time graph of a car which starts from rest.

  1. Calculate the speed of the car at \(10\) seconds.
  2. Find the value of \(u\), if the total distance covered in the first \(40\) seconds is \(1000\) m.
  3. Draw the distance-time graph of the car in the axes below.
