To solve this problem we will apply the second law of kinematics that describes the position as a function of speed, time and its acceleration, as
Here,
= Initial velocity
t = Time
a = Acceleration
Our values are,
Replacing we have that
From this expression we could determine the position traveled, without considering that the given speed is the same assumed in the term of acceleration. Under this consideration we would have to v = 4m / s
The answer will be
(1) correct
(2) correct
(3) the force of the soccer ball on the net
(4) Will not change
Hope this help

Send a pic of it so i can mark it.
Explanation:
It would be the 2nd one because the higher the farther away from the equator. <span />
If you have 12 atoms of hydrogen before a chemical reaction, the number of hydrogen atoms that will be present after the chemical reaction is 12 atoms.
The Law of Conservation of Mass (LOCOM) states that mass is neither created nor destroyed before and after any chemical reaction.
According to the Law of Conservation of Mass (LOCOM), a balanced chemical equation requires that the number of atoms on the reactant side must be equal to the number of atoms on the product side of any chemical reaction.
In this context, a chemical reaction having 12 atoms of hydrogen as reactants at the beginning, should also produce a total of 12 atoms of hydrogen as products at the end of the chemical reaction.
