Usually, Tony travels to Bunbury from Perth city in 2.50 hours. One day he increases his
average speed by 12.0 km/h and takes 22.5 minutes less time to reach Bunbury.
(a) What was his usual average speed? What was the distance travelled?
(b) On the way he stopped at a rail crossing (6.00 m wide) and a train (total length 144m)
decelerating at -0.585 ms2 just entered the crossing with a velocity of 13.7 m s¹. Sketch
a diagram and find the minimum time for the last carriage of the train to clear the
crossing.
