In ancient wars, heavy rocks are thrown horizontally from the wall as weapons. f the initial speed of a rock is 3 m/s , how many meters will it travel horizontally from a wall 25 meters abov the ground after 2 seconds(neglect air resistance, g=9.8m/s2)

The horizontal distance traveled by the rock from the wall after 2 seconds is 6m.

Explanation:

Given;

initial speed of the rock, u = 3 m/s

height of the wall, h = 25 m

time of travel, t = 2 seconds

The horizontal distance is determined as follows;

X = ut + ¹/₂gt²

where;

g is acceleration due to gravity, horizontal distance is not affected by gravity, g = 0

X = ut

X = 3 x 2

X = 6 m

Therefore, the horizontal distance traveled by the rock from the wall after 2 seconds is 6m.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

i will answer your question if you answer mine
