Answer:
float
Explanation:
The mass of the cube with volume 125 ml = 125 cm³= 20g.
The Mass of 125 ml of water is about 125g.
The same volume of water is heavier than the cube.
The first thing you should do in this case is to realize that you have two different materials.
First we make a free body diagram.
Then, we use the definitions of mechanics to find the forces.
Finally we substitute the values to find the normal stress due to the load.
Solution attached.
The only thing that definitely happens in every such case is:
The container becomes heavier.
The equation that would allow us to calculate for the acceleration given the distance is written below,
a = (Vf² - Vo²) / 2d
where a is the acceleration, Vf is the final velocity, Vo is the initial velocity, and d is distance.
Substituting the known values,
a = ((84 ft/s)² - (72 ft/s)²) / 2(180 ft) = 5.2 ft/s²
Then, the equation that would relate the initial velocity, distance, acceleration and time is calculated through the equation,
d = Vot + 0.5at²
Substituting the known values,
180 = 72(t) + 0.5(5.2)(t²)
The value of t from the equation is 2.3 s
<em>ANSWER: 2.3 s</em>
