The initial speed of the boy's thrown is determined as 16.03 m/s.
<h3>Initial speed of the boy's throw</h3>
The initial speed of the throw is calculated as follows;
h = vt - ¹/₂gt²
4 = 3t - (0.5)(9.8)(3)²
4 = 3t - 44.1
3t = 48.1
t = 48.1/3
t = 16.03 m/s
Thus, the initial speed of the boy's thrown is determined as 16.03 m/s.

Answer:
If I had one wish, I would wish to have actual human equality, not as something that covers up the dirty truths of this world, but to have actual peace and friendship between each and every race.
Answer:
The Periodic Law states that the physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number.
Answer:
The rate of the forward reaction is equal to the rate of the reverse reaction
Explanation:
Equilibrium is a condition in which the net force for change is zero.
In chemistry, equilibrium exists when reactant concentrations in a reaction are not changing. This condition means the reaction proceeding left to right in the reaction equation is producing products at the same rate those products are being used up by the reaction proceeding right to left. In short, the rate of the forward reaction is equal to the rate of the reverse reaction.
