The motion of an autombile acceleration away from traffic light is represented by the funciton d(t) = 9t^2, where t is the time in seconds and d(t) is the distanct covered by the automobile. Approximately how many seconds does it take for the automobile to travel 180 feet?
------------
d(t) = 9t^2 = 180
t^2 = 20
t =~ 4.472 seconds
