To find the time, tr, it takes for the runner to cross the finish line, we can use one of the kinematic equations that relate displacement, initial velocity, acceleration, and time. Since the runner starts from rest, his initial velocity is zero, so we can use the equation:
Δx=v0t+21at2
where Δx is the displacement, v0 is the initial velocity, a is the acceleration, and t is the time. Plugging in the given values of Δx=d, v0=0, and a=ai, we get:
d=0+21ait2
Solving for t, we obtain:
t=ai2d
This is the expression for the time, tr, it takes for the runner to cross the finish line, in terms of d and ai.

Earth's northern axis is tilted away from the Sun during the summer.
The North Pole is tilted away from the Sun during the summer.
Answer:
The northern hemisphere receives more direct sunlight during the summer.
Answer: 90 degrees
Explanation:
The projectile will have the greatest air time and height when the launch is the most vertical. At 90 degrees, the launch is all vertical.
