A train moves along a straight track with constant acceleration. Three telegraph poles are set at equal intervals beside the track at points AAA, B B\,B and CCC, where AB=50AB = 50AB=50 m and BC=50BC = 50BC=50 m. The front of the train passes A A\,A with speed 22.5 m s−1s^{-1}s−1, and 2 s later it passes BBB.
Find the acceleration of the train.
Find the speed of the front of the train when it passes CCC.
Find the time that elapses from the instant the front of the train passes B B\,B to the instant it passes CCC.
