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.

it lies in geometrical centre....
Answer: 12 m/s
Explanation:
If we ignore air resistance, gravity alone will reduce the upward velocity to zero at the top of the flight. As gravity is a conservative force, it will return exactly the same amount of energy to the tennis ball when it returns to the original elevation.
<span>If your speed changes from 10 km/h to 6 km/h, you have a negative acceleration. The correct option among all the options that are given in the question is the first option or option "a". The other choices are totally incorrect. I hope that this is the answer that has actually come to your help.</span>
