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.
