Answer:
B. IT should have a very broad focus with many variables.
Answer:
Because of height and lower atmospheric pressure.
Explanation:
Atmospheric pressure affects aerodynamic drag, lower pressure means less drag. At the altitude of Denver the air has lower pressure, this allows baseball players to hit balls further away.
Another aerodynamic effect is the Magnus effect. This effect causes spinning objects to curve their flightpath, which is what curveball pitchers do. A lower atmospheric pressure decreases the curving of the ball's trajectory.
Answer:
12 m/s
Explanation:
First, find the time it takes for the ball to fall 2.0 m.
y = y₀ + v₀ t + ½ at²
0 = 2.0 + (0) t + ½ (-9.8) t²
0 = 2 − 4.9t²
t = 0.639
Find the velocity needed to travel 7.8 m in that time.
x = x₀ + v₀ t + ½ at²
7.8 = 0 + v₀ (0.639) + ½ (0) (0.639)²
7.8 = 0.639 v₀
v₀ = 12.2
Rounded to two significant figures, the initial velocity is 12 m/s.
It measures the capacity of the heart, lungs, and blood to transport oxygen to the working muscles, and measures the utilization of oxygen by the muscles during exercise. I hope I wasn’t too late. Lol
