An object moves from position X = -1.88 m to X = -4.27 m. What was its displacement? (Unit=m)

The answer should be -2.39 m.

Explanation:

The object starts at -1.88 m and ends up at -4.27 m. Using simple math, we can add -4.27 m and 1.88 m by making -1.88 m a positive position. If you do the math correctly, you will get -2.39 m. Now to test this, you can simply add -1.88 m and -2.39 m and your answer will be -4.27 m.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
