Angle bullet and vertical is 60° given. So angle between horizontal and bullet will be 90°-60°=30°= a (let)
Initial velocity u = 9.8m/s (given)
Time of flight T is given by
T = 2u×sina/g
g= 9.8m/s^2 and sin30° = 1/2
So T = (2×9.8×1)/9.8×2 = 1 second
Maximum height H is given by (u×sina)^2/2g
So H= (9.8×1/2)^2/2×9.8
= 24.01/19.6 = 1.225m
