A goods train passes through a station at a steady speed of 10ms¯¹ at time t = 0. An express train is at rest at the station. The express train leaves the station with a uniform acceleration of 0.5ms¯² just as the goods train goes past. Both trains move in the same direction on straight, parallel tracks. At which time t does the express train overtake the goods train?
