5. A stone is thrown from modelled by the function a) Determine the averag Round your answer t A stone is thrown from the top of a bridge into a lake below such that its height, \(h\) , in metres, can be modelled by the function \(h ( t ) = 60 - 8 t - 4.9 t ^ { 2 }\) , where \(t\) is measured in seconds. a) Determine the average rate of change of the height of the stone in the first \(3 s\) after it was dropped. Round your answer to one decimal place. (3 points)
