Answer:
It will take 15.55s for the police car to pass the SUV
Explanation:
We first have to establish that both the police car and the SUV will travel the same distance in the same amount of time. The police car is moving at constant velocity and the SUV is experiencing a deceleration. Thus we will use two distance fromulas (for constant and accelerated motions) with the same variable for t and x:
1.
2.
Since both cars will travel the same distance x, we can equal both formulas and solve for t:
We simplify the fraction present and rearrange for our formula so that it equals 0:
In the very last step we factored a common factor t. There is two possible solutions to the equation at and:
What this means is that during the displacement of the police car and SUV, there will be two moments in time where they will be next to each other; at (when the SUV passed the police car) and (when the police car catches up to the SUV)
The volume of an object that has a mass of 16 g and a density of 12 g/cm³ is 1.33cm³.
<h3>How to calculate density?</h3>
Density is a measure of a substance mass in relation with it's volume, which means that it can be calculated by dividing the mass of the substance by volume as follows:
Density = mass ÷ volume
According to this question, an object has a mass of 16 g and a density of 12 g/cm³. The volume can be calculated as follows:
Volume = 16g ÷ 12g/cm³
Volume = 1.33cm³
Therefore, the volume of an object that has a mass of 16 g and a density of 12 g/cm³ is 1.33cm³.
