3. Kian is driving 48 miles per hour and is speeding up to merge onto the highway. He gradually accelerates at a rate of 7 miles per hour for several seconds. The formula s = ut + 2at can be used to calculate the distance, s, an object travels in t seconds. In this formula, u represents the initial velocity, and a represents a constant acceleration. a. Substitute the initial velocity and constant acceleration into the formula to write an equation to represent the distance Kian travels. b. Use the Quadratic Formula to determine the roots of the equation. What do the roots represent in the context of the problem situation? Explain your reasoning.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
