The distance, d in meters, that an accelerating object travels is given by
d=1/2*a*t^2
, where a is the acceleration rate in meters per second squared
and t is the time in seconds. A motorbike accelerates from a stop with
an acceleration of 40 meters per second squared over a distance of 60
meters. About how many seconds did the motorbike travel?
