Question

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?

Answer 1

No, the projectile is not a freely falling body. The acceleration in the vertical direction is approximately 9.8 m/s^2 downward. The acceleration in the horizontal direction is zero.

Step-by-step explanation:

(a) No, the projectile is not a freely falling body. A freely falling body experiences a constant acceleration due to gravity in the vertical direction, whereas a projectile experiences a parabolic trajectory due to its initial velocity and angle of launch.

(b) The acceleration in the vertical direction is equal to the acceleration due to gravity, which is approximately 9.8 m/s2, and it acts downward.

(c) The acceleration in the horizontal direction is zero because there is no change in speed or direction in that direction.

Answer 2

A) No

B)-9,81 m/s^2

C)0 m/s^2

Step-by-step 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.
