A projectile is fired horizontally from the top of a building in Earth gravity with an initial speed v₀. In the absence of air resistance, which of the graphs is representative of the projectile's motion? A) 1) B) 2) C) 3) D) 4) E) 5)

Quizplus · Accepted Answer

The projectile fired horizontally from the top of a building will undergo projectile motion in which it will follow a parabolic path. The vertical component of its velocity will be affected by gravity and will cause the projectile to accelerate downwards with a constant acceleration of 9.8 m/s^2. However, the horizontal component of its velocity will remain constant throughout its motion. Thus, the graph that best represents this motion is graph 1), which shows a parabolic path indicating a constant horizontal velocity and a downward acceleration due to gravity.
