A stone projected at angle `theta` with horizontal from the roof of a tall building falls on the ground after three seconds. Two second after the projection it was again at the level of projection. Then the height of the building

A stone projected at angle 'theta' with horizontal from the roof of a tall building talls on the ground after three second. Two second after the projection it was again at the level of projection. Then the height of the building is -

A stone is dropped from the roof of a building takes 4s to reach ground. The height of the building is

A stone projected from ground level falls on the ground after "4" seconds.Then the height of the stone 1 second after the projection is (g=10m/s^(2))

A stone is thrown horizontally from the top of a cliff and strikes the ground after 5 seconds, at an angle of 45^(@) with the horizontal . Calculate (i) height of the cliff. (ii) speed of projection of the stone .

A stone projected at an angle of 60^@ from the ground level strikes at an angle of 30^@ on the roof of a building of height h . Then the speed of projection of the stone is:

A stone projected at an angle of 60^@ from the ground level strikes at an angle of 30^@ on the roof of a building of height h . Then the speed of projection of the stone is:

A stone projected at an angle of 60^@ from the ground level strikes at an angle of 30^@ on the roof of a building of height h . Then the speed of projection of the stone is:
