Aprojectile 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 m/s2(c) what is its acceleration in the horizontal direction?

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.

the answer is c.)

explanation:

frequency or wavelenth of em radiation in a vacuum
