The positions of the cars a few minutes after they start racing is shown on the position time graph below. North is taken as positive. Use the graph to answer the questions that follow. Use only the correct letter(s) in your answer. 3.1.1 Which of the cars are travelling at a constant velocity? (3) 3.1.2 Which of the cars are slowing down? (1) 3.1.3 Which of the cars are travelling south? (2) 3.1.4 Which of the cars has the highest average speed? (1) 3.1.5 Describe what happened at point P on the graph. (2) 3.2 Another car decides to join the race and speeds up, driving due North, to join the other cars. However, she sees that the police have set up a road block and brakes suddenly, hoping to stop before she reaches the road block which is 500m away from her starting point.The velocity-time graph below shows the first 20 seconds of the motion of the car. 3.2.1 Define the term acceleration. (2) 3.2.2 Use the information off the graph to determine the acceleration of the car in thefirst 5 seconds. (3) 3.2.3 Use the units on the axes to show that the area below the velocity time graph is equivalent to the distance travelled. (2) 3.2.4 Determine the distance travelled in the 20 second period. Show working clearly. (4) 3.2.5 Calculate the acceleration from points C-D. (3) 3.2.6 Use calculations to determine whether he will be able to stop before he reaches the roadblock (500m away from his starting point) if he continuous to brake at the same rate. Show your working clearly. (4) Unfortunately for the driver, a frame by frame camera captures part of his motion. This is shown in the footage below. The camera records a photograph every 0,005s. 3.2.7 Which portion of the graph can be linked to the photograph? Give a reason for your answer. (2) 3.2.8 Sketch a position-time sketch graph that shows the motion of the graph for this interval. (3) The camera is set to flash if the instantaneous velocity at any point exceeds 20 m.s-1. The driver says that his average velocity over the time period was only 10 m.s-1 and thus he should not be fined. 3.2.9 Explain what the difference is between average and instantaneous velocity. (2) 3.2.10 Calculate the average velocity from the photograph. (3) 3.2.11 Give a reason why the traffic department considers this to be the instantaneous velocity of the car. (1) [38]

Here аre the 4 types оf resоurces: Lаnd (аll natural resоurces), Labor (work brought about by the physical and mental talents that people contribute), Capital (produced goods), and Entrepreneurship (the talent that people have for organizing the resources or land, labor, and capital to produce goods or services). Give an example of one resource here in CA that we don't have an abundance of. In fact, we are encouraged to conserve this resource to the best of our abilities.
