               1. The speed - time graph of a car is given here. Using the data in the graph calculate
               the total distance covered by the car.





















               (a) 1250 m


               (b) 875 m

               (c) 1500 m


               (d) 870 m

               2. A car is travelling at a speed of 90 km/h. Brakes are applied so as to produce a
                                                  2
               uniform acceleration of – 0.5 m/s . Find how far the car will go before it is brought to
               rest?
               (a) 8100 m
