Answer:
Therefore, the time it takes for the bullet to strike the ground is 0.582 seconds
Explanation:
h = ut + 0.5(gt²)
where;
h is the height above ground = 1.66 m
u is the initial velocity of the bullet vertically = 0
g is the acceleration due to gravity = 9.8 m/s²
From the equation above
1.66 = 0*t + 0.5*9.8*t²
1.66 = 4.9t²
t² = 1.66/4.9 = 0.3388
t = √0.3388
t = 0.582 seconds
Therefore, the time it takes for the bullet to strike the ground is 0.582 seconds
