Question

An object is launched from the ground, with an initial velocity of vo m/s, at an angle from the horizontal. What is its acceleration in the x direction (horizontal) after it is launched?

A) 0 m/s²
B) Vo m/s²
C) Vo(cosθ) m/s²
D) Vo(sinθ) m/s²

Answer 1

The horizontal acceleration of an object launched from the ground is 0 m/s²

Step-by-step explanation:

The horizontal acceleration of an object launched from the ground is 0 m/s², Option A.

Since there is no horizontal acceleration, the initial and final horizontal velocities are the same, resulting in zero acceleration in the x direction.

This is because there are no external forces acting horizontally on the object, so its horizontal velocity remains constant throughout its trajectory.
