Question

Jon Snow shoots an arrow horizontally at 32.0 m/s from the top of the wall, 295 m above the ground. How long will the arrow be in the air? How far from the wall will it land?

Answer 1

Step-by-step explanation:

It is given that,

Velocity of arrow, v = 32 m/s

Height above ground, h = 295 m

Let t is the time taken by arrow in air. It is given by :

`h=ut+(1)/(2)at^2`

a = g

Initially, u = 0

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

`t=\sqrt{(2* 295)/(9.8)}`

t = 7.75 seconds

Let it land at a distance of d. It is given by :

`d=v* t`

`d=32* 7.75`

d = 248 meters

Hence, this is the required solution.
