6. The students in a physics class are performing an experiment to determine the acceleration due to gravity. They drop water balloons from the top of a building and estimate the time at which the balloon hit the ground. After analyzing all of their data, they produce the model h() = -S² + 30 to model the height of a balloon in metres t seconds after it has been dropped. What is the best estimate for the instantaneous rate of change in the height of a balloon 1 s after it has been dropped? a. - 20 m/s b. - 10 m/s c. - 5 m/s d. 5 m/s

Question
6. The students in a physics class are performing an experiment to determine the acceleration due to gravity. They drop water balloons from the top of a building and estimate the time at which the balloons hit the ground. After analyzing all of their data, they produce the model h() = -5r? + 30 to model the height of a balloon in metres t seconds after it has been dropped. What is the best estimate for the instantaneous rate of change in the height of a balloon 1 s after it has been dropped? a. - 20 m/s c. - 5 m/s d. 5 m/s b. - 10 m/s
