A particle is dropped from a height h. Another particle which is initially at a horizontal distance d from the first is simultaneously projected with a horizontal velocity u and the two particles just collide on the ground. Then

A particle is projected from a point on the level ground and its height is h when at horizontal distances a and 2 a from its point of projection. Find the velocity of projection.

A particle is projected from a point on the level ground and its height is h when at horizontal distances a and 2 a from its point of projection. Find the velocity of projection.

A particle (A) is dropped from a height and another particles (B) is thrown into horizontal direction with speed of 5m/s sec from the same height. The correct statement is

A particle (A) is dropped from a height and another particles (B) is thrown into horizontal direction with speed of 5m/s sec from the same height. The correct statement is

A particle is projected from point A on the ground at an angle theta with horizontal. Another particle is projected from point B simultaneously from height 4 H above point A with same velocity A and B are in the same vertical plane, where H is the maximum height attained by the particle A, Both the particle collide at the same time on the ground. Find the angle at which particle B is projected with hoizontal.

Assertion Particle-1 is dropped from a tower and particle-2 is projected horizontal from the same tower. Then both the particles reach the ground simultaneously. Reason Both are particles strike the ground with different speeds.

A body, rpojected horizontally with a speed u from the top of a tower of height h , reaches the ground at a horizontally distance R from the tower. Another body, projected horizontally from the top of a tower of height 4h , reaches the ground at horizontal distance 2R from the tower. The initial speed of the second body is
