  3. Find the distance that the stone falls during the first 4 seconds of its motion. (3 marks)
  4. Find the speed of the stone when it has been falling for 4 seconds. 2 A car travels along a straight horizontal road. The motion of the car can be modelled as three separate stages. During the first stage, the car accelerates uniformly from rest to a velocity of \(10 \mathrm {~ms} ^ { - 1 }\) in 6 seconds. During the second stage, the car travels with a constant velocity of \(10 \mathrm {~ms} ^ { - 1 }\) for a further 4 seconds. During the third stage of the motion, the car travels with a uniform retardation of magnitude \(0.8 \mathrm {~m} \mathrm {~s} ^ { - 2 }\) until it comes to rest.
  5. Show that the time taken for the third stage of the motion is 12.5 seconds.
