An object is thrown horizontally from a point from a tower and hits the ground later at . The line from to makes an angle of with the horizontal. The initial velocity of the object is: (take

A body is projected horizontally from the top of a tower with an initial velocity . It hits the ground at angle . What is the vertical component of velocity when it strikes the ground?

A bomber plane moving at a horizontal speed of releases a bomb at a height of above ground as shown. At the same instant, a hunter of negligible height starts running from a point below it, to catch the bomb with speed . After two seconds he realised that he cannot make it, he stops running and immediately holds his gun and fires in such a direction, so that just before the bomb hits the ground, a bullet will hit it. What should be the firing speed of bullet. (Take )

A ball is projected from a certain point on the surface of a planet at a certain angle with a horizontal surface. The horizontal and vertical displacement and vary with time in second as:
and
The maximum height attained by the ball is:
