A body projected horizontally with a velocity v from a height h has a range R .With what velocity a body is to be projected horizontally from a height h//2 to have the same range ?

Discuss the motion of a body when projected horizontally from a height .

Assertion : A body droped from a given height and another body projected horizontal from the same height strike the ground simultaneously Reason : Because horizontal velocity has no effect in the vertical direction .

If in a projection motion, the maximum height is equal to a horizontal range, find the angles of projection [tan^(-1) (4) = 76^(@)]

A particle is projected from ground with speed u and at an angle theta with horizontal. If at maximum height from ground, the speed of particle is 1//2 times of its initial velocity of projection, then find its maximum height attained.

A glass marble projected horizontally from the top of a table falls at a distance x from the edge of the table. If h is the height of the table, then the velocity of projection is

Does the escape speed of a body from the earth depend on (a) the mass of the body. (b) the location from where it is projected. © the direction of projection, (d) the height of the location from where the body is launched?

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 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 ball projected from ground at an angle of 45^(@) just clears a wall infront. If point of projection is 4m from the foot of wall and ball strikes the ground at a distance of 6m on the other side of the wall, the height of the wall is
