Question

A train 200m long moving at constant acceleration crosses a bridge 300m long. it enters the bridge with speed of 3m/s and leaves with speed of 5m/s.what is the time taken to cross the bridge

Answer 1

The initial speed = 3m/s

The final speed = 5m/s

Change in speed is = 5 - 3 = 2m/s

The total distance covered = 300 + 200 = 500m

Time = Distance / speed

Time = 500/2 = 250 seconds
