Baseball Bonanza Vernon Wells hits a baseball that travels for 142 m before it lands. The flight of the ball can be modelled by a quadratic function in which x is the horizontal distance the ball has travelled away from Vernon, and h(x) is the height of the ball at that distance. There are many quadratic equations you could use to model the distance and height, but you want to find one that is close to reality. What is the function that will model the height of Vernon's ball accurately over time? A. Assume that the ball was between 0.6 m and 1.5 m above the ground when it was hit. a) What would h(142) be? b) What happens when x = 0? c) What are the possible values for h(x) when x = 0? d) What would be a good range of values for the height of the ball? Are some values for the height unreasonable? B. Explain why each function is not a good model of the situation, and support your claim with reasons and a well-labelled sketch. a) h(x) = -0.5x(x - 142) b) h(x)= -0.5x + 71x + 1 c) h(x) = -0.0015x +0.213x + 1.2 C. Determine an equation that models the path of the ball, given this additional information: a) The ball was 1.2 m off the ground when it was hit. b) The ball reached a maximum height of 17 m when it was approximately 70 m away from Vernon. Explain the method you are using to get the equation, and show all of your steps. Why did you approach the problem this way? Task Checklist Did you state your reasons that the given models were not reasonable? Did you draw a well- labelled graph, including some values? Did you show your work in your choice of method for part C? Did you support your choice of method in part C?
