Answer:
Therefore letter <u>C is the correct answer.</u>
Explanation:
In a projectile motion the total time in the air can be calculated using the following equation:
We analyze the y-component motion.
When the final velocity (v(f)) is equal to zero we calculate the upward time and multiplying it by 2 we find the total time in the air. So we will have:
We can see that the <u>total time is directly proportional to the angle</u>, then when <u>θ increase t increase.</u>
Therefore letter C is the correct answer.

a. The wheel accelerates uniformly, so its constant acceleration is equal to the average acceleration:
b. Yes. Since
then multiplying by 2 means we double the change in angular speed, but the wheel starts from rest so only the final angular speed
gets doubled.
