At the highest point, the speed will be the least. Then the correct option is A.
<h3>What is kinematics?</h3>
It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
A ball is hit at an angle of 30°.
Then the speed in the x-direction will not change with respect to time because acceleration is zero.
But the speed in the y-direction depends upon the acceleration due to gravity.
If the project an object with an angle, then as it goes upward direction the speed decreases and becomes zero at the highest point then it falls down with increasing speed.
At the highest point, the speed will be the least. Then the correct option is A.
More about the kinematics link is given below.

Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
![Z_{\alpha/2}= Z_{0.10/2} = 1.645](https://tex.z-dn.net/?f=Z_%7B%5Calpha%2F2%7D%3D%20Z_%7B0.10%2F2%7D%20%3D%201.645)
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
![M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=M.O.E%20%3D%20Z_%7B%5Calpha%2F2%7D%20%5Ctimes%20%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
![0.10 = 1.645 \times \sqrt{{\dfrac{0.5(1-0.5)}{n}](https://tex.z-dn.net/?f=0.10%20%3D%201.645%20%5Ctimes%20%5Csqrt%7B%7B%5Cdfrac%7B0.5%281-0.5%29%7D%7Bn%7D)
Squaring both sides; we have:
![0.10^2 = 1.645^2 \times {\dfrac{0.5(1-0.5)}{n}](https://tex.z-dn.net/?f=0.10%5E2%20%3D%201.645%5E2%20%5Ctimes%20%7B%5Cdfrac%7B0.5%281-0.5%29%7D%7Bn%7D)
![0.01 = 2.706025 \times \dfrac{0.25}{n}](https://tex.z-dn.net/?f=0.01%20%3D%202.706025%20%5Ctimes%20%5Cdfrac%7B0.25%7D%7Bn%7D)
![n= 2.706025 \times \dfrac{0.25}{0.01 }](https://tex.z-dn.net/?f=n%3D%202.706025%20%5Ctimes%20%5Cdfrac%7B0.25%7D%7B0.01%20%7D)
n = 67.65
Therefore, the required sample size = 67.65
That would be true because of momentum but the seat belt would slow this you would still hit the dash or a steering wheel's air bag system if it is equipped with one
