1. The height of a shotput over time can be modelled by the function h(1) =-4.91- +8+1.5 Height vs. Time The graph of this function is, Height Time (s) a) The four graphs below each have a coloured line/line segment added to the graph above. One of the graphs has the line/line segment that could be used to calculate the average rate of change of the height of the shotput between 1=0 and t=0.5s. What colour is this line? (tell me the location of the graph if colour-blindness is an issue) Heightus. Time Height jm) Height(m) 0.5 Time (s) Time (s) Heightvs. Time Height we J 31 Height (m) Height im 0.5 1.5 0.5 Time (3) Time (3)b) Determine the average rate of change of the height of the shotput between 1 :13 and r = {15 seconds. You may use the graph chosen in a] to get an estimate of the AROC or make use of the function above in order to get a more accurate AROC. Either method will allow you to achieve full marks for this question. Don't do both. Include appropriate units in your answer. Show your work. c) One of the graphs above has a liner'line segment that would allow you to nd an ARUC that is negative. i} List the colour of the line. ii) What does it mean if the AROC of the height of a shotput is negative
