A stone is dropped form 100 m high cliff. Another stone is thrown upward from ground with a velocity 10m/s. At what time both the stones will meet each other ?

A stone is dropped into water from a bridge 44.1 m above the water. Another stone is thrown vertically downward 1 sec later. Both strike the water simultaneously. What was the initial speed of the second stone

A stone is dropped in a well 107 m deep. If the splash is heard 5 seconds after the stone is dropped, then calculate the speed of sound in air.

A stone is dropped into a well 44.1 deep. The sound of splash is heard 0 . 13 seconds after the stone hits the water. What should be the velocity of sounds in air .

A stone is dropped into a well. If the depth of water below the top be h and velocity of sound is v then the splash in water is heard after T sec. Then:

A stone is dropped from the top of a tower of height h . Aftre 1 s another stone is droppped from the balcony 20 m below the top. Both reach the bottom simultaneously. What is the value of h ? Take g=10 ms^(-2) .

A stone is dropped from the top of a tower. When it crosses a point 5 m below the top, another stone is let fall from a point 25 m below the top. Both stones reach the bottom of the tower simultaneously. Find the height of the tower. Take g = 10 m//s^2.

A stone is dropped from a height h. Simultaneously, another stone is thrown up from the ground which reaches a height 4 h. The two stones cross each other after time
