5. Refer to the formulae, data and relationships booklet (open book exam) 6. You may use a calculator 7. You may use an English language dictionary | Fig. 1.1 shows how the speed of an object varies during a period of 30 s. 30 20 F Calculate the speed of the object at the start, time = 0 s. at the end, time = 30 b) Describe what, if anything. is happening to the speed during the period 10 s to 25 s. Determine the distance travelled in the last 5s. d) The total distance travelled during the 30 Sis 750 m. Calculate the average speed of the object during the 30 s. e) Calculate the area under curve up to the time. Explain what this 2 represents
