Question
A particle a is projected form the ground with an initial velocity of 10 m/s at an angle of 60° with horizontal. From what height h should an another particle B be projected horizontal with velocity 5 m/s so that both the particles collides at point C if both are projected simultaneously 
- 10 m
- 30 m
- 15 m
- 25 m
The correct answer is: 15 m
