CE and DF are two walls of equal height (20 meter) from which two particles A and B or same mass are projected as shown in the figure. A is projected horizontally towards left while B is projected at an angle `37^(@)` (with horizontal towards left) with velocity `15 m//sec`. If A always sees B to be moving perpendicular to EF then the range of A on ground is

Two particles A and B having different masses are projected from a tower with same speed. A is projected vertically upward and B vertically downward. On reaching the ground

Two particles A and B having different masses are projected from a tower with same speed. A is projected vertically upward and B vertically downward. On reaching the ground

Two projectiles A and B are projected with angle of projection B. If R_A and R_B be the horizontal range for the two projectile then.

Two particles A and B projected simultaneously from a point situated on a horizontal place. The particle A is projected vertically up with a velcity v_(A) while the particle B is projected up at an angle 30^(@) with horizontal with velocity v_(B) . After 5s the particles were observed moving mutually perpendicular to each other. The velocity of projection of the particle v_(A) and v_(B) respectively are:

Two bodies A and B are projected sqrt2 u and u respectively.They cover the same horizontal range.If body A is projected at 15^@ with horizontal,then what is the angle of projectio of bodyB?

A particle is projected towards the north with speed 20 m//s at an angle 45^(@) with horizontal. Ball gets horizontal acceleration of 7.5 m//s^(2) towards east due to wind. Range of ball (in meter) will be

A particle is projected with velocity 50 m/s at an angle 60^(@) with the horizontal from the ground. The time after which its velocity will make an angle 45^(@) with the horizontal is
