Two projectiles A and B are projected at the same time in the same vertical plane. A is projected at a height of 2m above the ground making an angle of 30deg with the horizontal. B is projected with the velocity of 20m/s at an angle of 60deg with the horizontal. If they collide. Determine;
i) initial velocity of A (found it=11.5m/s)
ii)horizontal distance moved on the point of collision
iii)the time taken when they collide.
