Differentiate between distance and displacement using your own words. The velocity versus time graph for a car is shown below: (i) Describe the motion of the car along segments A, B and C on the graph. (ii) Calculate the total distance covered by the car. (iii) Sketch an acceleration versus time graph for the motion of the car. (.12 ) A 5 kg object travelling at 1.5 m/s collides with a 2 kg object that is travelling in the opposite direction at 0.5 m/s. The 5 kg object continues to move in the same direction after the collision but at a speed of 1 m/s. Find the speed and direction of the 2 kg object after the collision. What is the momentum of the 5 kg object after the collision
