FORM 3 PHYSICS REVISION SHEET 5. Two cars, Car A and Car B, participate in a drag race on a straight 1,000-meter track. The time taken by each car to complete the race is recorded at various checkpoints along the track as shown in the table below: Distance (m) Time for Car A (s) Time for Car B (9) 10 10 0 200 6 4.5 400 10 9 600 13 13.5 800 15 18 1000 17 22.5 Using the data provided, answer the following questions: a) Which car won the race? b) Calculate the average speed of Car A and Car B over the entire 1,000-meter distance. c) Sketch a Displacement vs Time graph for the Car A on the grid above: d) Using the graph determine between which two distance checkpoints was car A moving the slowest and the fastest. e) Calculate Car A' slowest speed and his highest speed. f) Calculate the average acceleration of Car A using the answers from part (e). 6. The student investigated the properties of a 15cm long spring and plotted the graph below. FORCE/N 30 25 20 15 10 20 40 60 80 Extension/cm a. Beyond which force Hooke's Law no longer applies?, b. Determine the spring constant of the spring using the graph. c. What's the entire length of the spring when a mass of 600g is attached to it. d. What force will be required to stretch another spring from 21 to 28 cm, if it has a spring constant that's 3 times greater than the one mentioned in part (b)?
