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)

Respuesta :

Answer:

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.
