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 temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
