Question 4 A. Joanna starting a car from rest accelerates uniformly to a speed of 50Km/h in 8 minutes. She maintains this speed for another 5 minutes, then applies the brakes and decelerates uniformly to rest in 3 minutes. Draw a velocity-time graph to show the different segments of the journey. B. Calculate the: i. acceleration in Km/h during the first 8 minutes of the journey. ii. deceleration in Km/h for the last 3 minutes of the journey: iii. total distance covered in Km for the entire journey iv. average speed for the entire journey in Km/h. Round answer to whole number. C. The diagram below, not drawn to scale, shows two parallel lines XY and ZW cut by a transversal line CD. Use the diagram to determine the unknown angles numbered 1 to 7 C 1540 2 W 4 Z D D. Construct triangle ABC, given that ZB = 60 and BC = 8cm . Measure and state the length of AB. Using triangle ABC, determine the number of rotational symmetry
