<h3><u>Answer;</u></h3>
Dilute solution
One gram of salt in 100 liters of water could be considered a <em><u>dilute solution</u></em>.
<h3><u>Explanation</u>;</h3>
- <em><u>A solution is a mixture that is composed of two or more substances. It is formed when one substance (solute) dissolves on another called solvent. </u></em>
- Solutions are homogeneous mixtures as the substances in it are always in the same phase. <em><u>A solution may be concentrated or dilute depending on the amount of solute or solvent in the solution.</u></em>
- <u>A dilute solution has more solvent that solute while a concentrated solution has more solute than the solvent. In this case, </u><em><u>a solution containing 1 g of slat which is the solute in a 100 liters of water is an example of dilute solution.</u></em>

Answer:
1.4 m/s
Explanation:
From the question given above, we obtained the following data:
Initial Displacement (d1) = 0.9 m
Final Displacement (d2) = 1.6 m
Initial time (t1) = 1.5 secs
Final time (t2) = 2 secs
Velocity (v) =..?
The velocity of an object can be defined as the rate of change of the displacement of the object with time. Mathematically, it can be expressed as follow:
Velocity = change of displacement /time
v = Δd / Δt
Thus, with the above formula, we can obtain the velocity of the car as follow:
Initial Displacement (d1) = 0.9 m
Final Displacement (d2) = 1.6 m
Change in displacement (Δd) = d2 – d1 = 1.6 – 0.9
= 0.7 m
Initial time (t1) = 1.5 secs
Final time (t2) = 2 secs
Change in time (Δt) = t2 – t1
= 2 – 1.5
= 0.5 s
Velocity (v) =..?
v = Δd / Δt
v = 0.7/0.5
v = 1.4 m/s
Therefore, the velocity of the car is 1.4 m/s
The solution for this problem is:
Let u denote speed.
Equating momentum before and after collision:
= 0.060 * 40 = (1.5 + 0.060) u
= 2.4 = 1.56 u
= 2.4 / 1.56 = 1.56 u / 1.56
= 1.6 m / s is the answer for this question. This is the speed after the collision.
