In astronomy and geography, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In mathematics, anything parallel to the horizon is called horizontal. Because vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.
F = m * a
F: force = 3N
m: mass = 1500g = 1.5kg
a: acceleration = __ m s⁻²
3 = (1.5) * a
3 / 1.5 = 1.5a / 1.5
a = 3/1.5
a = 2 m s⁻²
Hope this helps! :)
