Two particles A and B are projected simultaneously in a vertical plane as shown in figure. They collide at time t in air. Write down two necessary equations for collision to take place.

Two particles are projected simultaneously from the level ground as shown figure. They may collide after a time :

Two projectiles A and B are fired simultaneously as shown in figure. They collide in air at point at time t .Then

Two particles A and B of equal mass are projected simultaneously with speed 10 m/s each as shown in figure. Find the co-ordinate of COM at t=10 s

Two particles are projected with speed 4 m//s and 3 m//s simultaneously from same point as shown in the figure. Then :

Two particles A and B are projected in same vertical plane as shown in figure.Their initial positions (t=0) , initial spped and angle of projections are indicated in the diagram.If initial angle of projection theta_(B)=37^(@) , what should be initial speed of projection of particle B , so that it hits particle A . U_(A)=60m//s

Two particles are projected with speed 4m//s and 3m//s simultaneously from same point as shown in the figure. Then:
