Two stones are thrown from top of tower, one vertically upward and other downward with same speed. Ratio of velocity when they hit the ground is:

Two balls X and Y are thrown from top of tower one vertically upward and other vertically downward with same speed. If times taken by them to reach the ground are 6 s and 2 s respectively, then the height of the tower and initial speed of each ball are (g=10m//s^(2))

Two balls are projected simultaneously with the same speed from the top of a tower, one vertically up wards and the other vertically downwards. If the first bll strikes the ground with speed 20 m//s then speed of second ball when it strikes the ground is.

Two balls are projected simultaneously with the same velocity u from the top of a tower, one vertically upwards and the other vertically downwards. Their respective times of the journeys are t_(1) and t_(2) At the time of reaching the ground, the ratio of their final velocities is

Two balls are projected simultaneously with the same speed from the top of a tower, one vertically upwards and the other vertically downwards. They reach the ground in 9 s and 4 s, respectively. The height of the tower is (g=10 m//s^(2))

Two bodies are projected simultaneously with the same velocity of 19.6 m//s from the top of a tower one vertically upwards and the other vertically downwards. As they reach the ground, the time gap is

A person standing near the edge of the top of a building throws two balls A and B. The ball A is thrown vertically upward and B is thrown vertically downward with the same speed. The ball A hits the ground with speed v_A and the ball B hits the ground wiht a speed v_B . We have

From the top of a tower, a stone A is thrown upwards and a stone B is thrown downwards with the same speed. The velocity of stone A, on colliding with the ground is :

Two stones are thrown from the top of a tower, one straight down with an initial speed u and the second straight up with the same speed u. When the two stones hit the ground they will have speeds in the ratio.

A stone dropped from a building of height h and it reaches after t second on the earth. From the same building if two stones are thrown (one upwards and other downwards) with the same speed and they reach the earth surface after t_(1) and t_(2) seconds, respectively, then
