For a local celebration, a pvrotechnician lights some reworks. One rework left the ground at t = 0 seconds. The table below shows the height of the rework at various time. Time (sec) Height (ft) 294.4 a] What is its average velocitv over the interval [0, 2:? b) What is its average velocity over the interval :1, 3]? c) What is its average velocity over the interval [1, 5:? d) If the formula for the height of the rework is Mi) 2 161'.2 l 137.6t where his] is the height ofthe rework, in feet, after t seconds, use this equation to nd the average velocity of the rework on the interval :2, 6]
