Particle A is projected at 60 m s⁻¹ at 30° above the horizontal. At the same instant particle B is projected from a point 100 m away in the opposite horizontal direction with speed 50 m s⁻¹ at angle α above the horizontal. If they collide in air, take g=10 m s⁻². Which option correctly gives α, collision time and distance of the collision point from A?
