For the v-t graph shown above of a car, calculate the following:(note: you will need to estimate some values from the graph)a) The displacement of the car from t = 4 s to t = 10 s.b) The average velocity of the car for the first 7 seconds.c) The average acceleration fram t = 10 s to t = 15 s.d) The instantaneous velocity at t = 5 s.e) Describe the Motion from Os to 15s.
