Considering that while traveling on a road with a<u> final speed of 15 m/s</u>, and an<u> initial speed of 24 m/s</u>, with a given time <u>of 12 seconds.</u>
To calculate the acceleration, we apply the following formula:
α = Vf - Vo/t
We add our data into the formula and solve:
α = 15 m/s - 24 m/s/12 sec
α = -0.75 m/s²
Therefore, the acceleration of the car is -0.75 m/s².

Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction
Explanation:
-- On Earth, 1 kg of anything weighs 9.81 Newtons (2.205 pounds). It doesn't matter what substance comprises the kilogram.
-- Although their weights are identical, any mass of feathers occupies more volume than the same mass of iron, no matter where they happen to be located.
-- Iron is more dense than feathers, and more dense than a lot of other substances as well, too.

Answer:
She is not getting a good deal.
Explanation:
The equation that relates heat with mass, specific heat and temperature change of an object is 
.
Always convert temperature to Kelvin, although in our case it's not necessary because the 
will be the same, and we will leave the mass in grams because we will be getting 
units for specific heat, which we can compare to the one given for gold.
We then calculate the specific heat of the object in question:
Which shows it's not gold.
