Question

A bullet is fired horizontally from the top of an ocean-based drill site. If the air resistance is negligible and the vertical distance to the water is 35.0 m, what additional information is needed to determine the time required for the bullet to hit the water? (g = 9.81 m/s2)

Answer 1

no additional information required.

Step-by-step explanation:

given,

vertical height, h = 35 m

acceleration due to gravity, g = 9.8 m/s²

time taken by the bullet to fall in the water = ?

initial vertical velocity of the bullet = 0 m/s

using equation of motion for the time calculation

`s = ut + (1)/(2)gt^2`

`h= 0* t + (1)/(2)* g * t^2`

`t = \sqrt{(2h)/(g)}`

`t= \sqrt{(2* 35)/(9.8)}`

t = 2.67 s

The time taken by the bullet to fall in the ocean is equal to 2.67 s.

Hence, there is no additional information required.
