Quantitative:

1.Two trains are travelling between two stations at a constant speed of 25kmph.The stations are 50km apart .A bird traveling at 100kmph starts its flight along with one train and travels in the same direction until it meets the other train. It changes its direction and goes in the reverse direction until it meets the initial train. Find the distance travelled by the bird before the two trains collide.

2.A flight carrying food packets is flying at a height of 1960m from the ground. The speed of the flight is given. Find the time taken for a food packet dropped at that instance to hit the ground.

(Hint: Use s=ut+(at^2)/2.Initial velocity as 0 coz the dropped food packet does not have velocity in the vertical direction.)
