If a ball is thrown up in a moving train, it comes back to the person's hands. Why?

Two trucks are moving on parallel tracks. A person on one truck projects a ball vertically upward then path of the ball as seen by four observers : from the ground, from the second truck moving with same velocity as that first truck, from the second truck moving with speed greater than first one in same direction are :

(a) A ball is thrown vertically upward with speed 10 m//s and it returns to the ground with speed 8 m//s . Find the maximum height attained by the ball. (b) A ball is thrown vertically upward and if air resistance is half of weight of the ball, find the ratio of time of ascent and time of descent. (C) Two balls A and B (m_(A) = 2 m_(B) = 2 m) are thrown vertically upward. If air resistance is mg//2 , find ratio of maximum height attained by them.

The distance between two stations is 340 km. Two trains start simultaneously from these stations on parallel tracks to cross each other. The speed of one of them is greater than that of the other by 5 km/hr. If the distance between the two trains after 2 hours of their start is 30 km, find the speed of each train.
