Question

A gun fires two bullets at 60° & 30° with horizontal. The bullet strikes at same horizontal distance. The ratio of maximum height for the two bullets is in the ratio 

(a) 2:1

(b) 3:1 

(c) 4:1 

(d) 1:1

Answer 1

Answer is (b) 3:1

y_m = u² sin² θ/2g and y_m1y_m2 = sin² 60°/sin2 30° = (√3/2)² (1/2)² = 3/1.
