Final answer:
The bird will change direction and fly towards Train 2.
Step-by-step explanation:
The bird will change direction and fly towards Train 2.
When the bird reaches the midpoint between the trains, it will stay there and continue flying towards Train 2. This is because it is closer to Train 2, which is moving at a higher velocity. The bird will continue flying towards Train 2 until it reaches it and lands.
When two trains are approaching each other on the same track with velocities of 100 km/h and 50 km/h, their relative velocity is the sum of their individual velocities, which is 150 km/h. The bird starts flying from the first train towards the second train. The relative velocity of the bird with respect to the second train is the difference between the velocity of the bird and the velocity of the second train. The bird is essentially moving in the opposite direction of the second train.
Assuming the bird's velocity is v, its relative velocity with respect to the second train is (v - 50) km/h. When the two trains are at a distance of 300 km from each other, the time it takes for the bird to cover this distance is given by the formula time = distance / relative velocity. Therefore, the bird will reach the second train in 2 hours, given that (300 km) / (v - 50 km/h) = 2 hours.
