1. The amount of horsepower needed to overcome a wind drag on a certain automobile is given by: 

\( H ( s ) = 0.005 s ^ { 2 } + 0.007 s - 0.031 \) , where \( s \) is the speed of the car in miles per hour. How much horsepower is needed to overcome the wind drag on this car if it is traveling \( 55 \) miles per hour? (Hint: Round to the nearest hundredth) 

\( H ( s ) = \) 

By completing the square, at what speed will the car need to use \( 225 \) horsepower to overcome the wind drag? (Hint: Leave in fraction form until the end, and then round to the nearest hundredth) 

\( s = \) mph
