A man standing on the edge of the terrace of a high rise building throws a stone, vertically up with at speed of `20 m//s`. Two seconds later, an identical stone is thrown vertically downwards with the same speed of `20 m`,. Then

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

A person, standing on the roof of a 40 m high tower, throws a ball vertically upwards with speed 10 m/s. Two seconds later, he throws another ball again in vertical direction (use g=10(m)/(s^2) ). Both the balls hit the ground simultaneously.

A person, standing on the roof of a 40 m high tower, throws a ball vertically upwards with speed 10 m/s. Two seconds later, he throws another ball again in vertical direction (use g=10(m)/(s^2) ). Both the balls hit the ground simultaneously.

A person, standing on the roof of a 40 m high tower, throws a ball vertically upwards with speed 10 m/s. Two seconds later, he throws another ball again in vertical direction (use g=10(m)/(s^2) ). Both the balls hit the ground simultaneously.

A woman stands on the edge of a cliff and throws a stone vertically downward with an initial speed of 10 m/s. The instant before the stone hits the ground below, it has 450 J of kinetic energy. If she were to throw the stone horizontally outward from the cliff with the same initial speed of 10 m/s, how much kinetic energy would it have just before it hits the ground ?

A person, standing on the roof of a 40m high tower, throws a ball vertically upwards with speed 10 m//s . Twp seconds later, he throws another ball again in vertical direction. (use g = 10 m//s^(2) ) Both the balls hit the ground simultaneously.

A stone is thrown vertically upwards with a speed of 20 m/s. How high will it go before it begins to fall? (g=9 .8 m//s^2)

A man standing on the edge of a cliff throws a stone straight up with initial speed (u) and then throws another stone straight down with same initial speed and from the same position. Find the relation of the speeds. The stones would have attained when they hit ground at the base of the cliff.
