You use a video to create a graph of the position of Usain Bolt from the starting line vs time from the start of the race, and you get the graph shown below.You use the graph to calculate what his position would have been at a time of 6 s. This process is known as:Question 7Select one:a.Extrapolationb.Interpolationc.Linearisationd.Estimatione.Analysis

Calculate the time taken for Bolt to reach each distance in the race according to the data in the table above.Distance (metres)020406080100Time taken (seconds)

Learning goal 1: As Usain Bolt began his world record-breaking 100 m sprint in 2009, the net force on his 94 kg body was 893 N.Calculate his acceleration, showing your working.

Calculate the distance travelled by the runner in the 7 s shown.

The above velocity / time graph shows a runner travelling at a constant speed, and then slowing to a stop.Calculate the distance travelled by the runner in the 7 s shown.

Part of race (metres)0 – 2020 – 4040 – 6060 – 8080 – 100Time taken (seconds)2.891.751.671.611.66Question 13(2 marks)SavedExplain in which twenty-metre segment Bolt had the highest average speed.Calculate the average speed in this segment to two decimal places.Note: Write the formula using "s" for average speed. Use the maths symbols icon to write the equation. Pressing the slash "/" in this mode will program a division line in your formula.
