A projectile is launched at some angle to the horizontal with some initial speed vi, and air resistance is negligible.(a) Is the projectile a freely falling body?Yes or No(b) What is its acceleration in the vertical direction? (Let up be the positive direction.)____? m/s2(c) What is its acceleration in the horizontal direction?

A projectile is an object to which an initial velocity has been communicated and has been released to perform a movement under the action of gravity. Projectiles that are close to Earth follow a very simple curved path that is known as a parable. To describe the movement it is useful to separate it into its horizontal and vertical components .

B)The Gravity acts to influence the vertical movement of the projectile

The movement of a projectile is a classic example of two-dimensional movement with constant acceleration in the vertical direction.

C) The horizontal movement of the projectile is the result of the tendency of any object to remain in motion at constant speed, So your horizontal direction acceleration is zero.

Answer:

A) No

B)-9,81 m/s^2

C)0 m/s^2

Explanation:

A free fallin object has only velocity on the vertical axis so any object that is moving in the Y and X axis has projetile motion not free falling, and when dealing with projectile motion the object is experiencing acceleration towards the ground of -9,81m/s^2 and in the Y axis, in the X axis there´s is only acceleration if the air is providing resistance, since it states that it isnot, then the accleration is 0.
