Two particles A and B are projected simultaneously from a fixed point of the ground. Particle A is projected on a smooth horizontal surface with speed v, while particle B is projected in air with speed v, while particle B is projected in air with speed `(2v)/(sqrt(3))`. If particle B hits the particle A, the angle of projection of B with the vertical is

Two particles A and B are projected simultaneously from two towers of heights 10 m and 20m respectively. Particle A is projected with an initial speed of 10 sqrt(2) m//s at an angle of 45^@ with horizontal, while particle B is projected horizontally with speed 10 m//s . If they collide in air, what is the distance d between the towers?

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 particles A and B are projected simultaneously in horizontal direction with speed 50 m//s and 100m//s respectively . If t_(A) and t_(B) are the time taken by the projectiles to hit the ground by the particles A and B respectively, then

Two particles A and B are placed as shown in figure. The particle A, on the top of tower, is projected horizontally with a velocity u and particle B is projected along the surface towards the tower, simultaneously. If both particles meet each other, then the speed of projection of particles B is [ignore any friction]
