Answer :
The time taken for the bullet to reach the ground is 0.447 s
What is free fall?
The falling of a body under the force of gravity only,it is not experienced by any external force.
Height from which the bullet id fired, h = 0.981 m
initial velocity of the bullet, u₁ = 981 m/s
Since it is fired parallel to the ground , the initial velocity u₁ does not have a vertical component
So it will be a free fall
Therefore the time taken to reach ground , t =√(2h/g)
t = √(2 * 0.981 / 9.81)
= √(1/5)
= √0.2
t = 0.447 s
Therefore the time taken for the bullet to reach the ground is 0.447 s
