The angles of two bullets from horizontal is 60 and 20 degrees and their velocity is also same. So, the height of two bullets is in the ratio of their angles.
Therefore,
Height for the two bullet is in ratio 60 : 30 = 2 : 1
Therefore,
Height for the two bullet is in ratio 60 : 30 = 2 : 1

- h=u²sin²α÷2g
- h1 ÷h2=sin²α1÷sin²α2
- sin60×sin60÷sin30×sin30
- ⁽√3÷2×√3÷2⁾÷1/2×1/2
- 3
- so the answer is 3:1
