A subway train accelerates from rest at one station at a rate of 1.30 m/s^2 for half of the distance to the next station, then d
ecelerates at this same rate for the second half of the distance. If the stations are 3200m apart, find the time of travel (in seconds) between the two stations.
<span>vf^2 = vi^2 + 2*a*d --- vf = velocity final vi = velocity initial a = acceleration d = distance --- since the airplane is decelerating to zero, vf = 0 --- 0 = 55*55 + 2*(-2.5)*d d = (-55*55)/(2*(-2.5)) d = 605 meters
The scientific advance that launched an ethical alert in the scientific community was the possibility of cloning animals, since it presents important questions, especially if such a project is extended to humans.
