Answer: D. 0.57
Explanation:
The formula to calculate the eccentricity of an ellipse is (assuming the moon's orbit in the shape of an ellipse):
Where:
is the apoapsis (the longest distance between the moon and its planet)
is the periapsis (the shortest distance between the moon and its planet)
Then:
This is the moon's orbital eccentricity
Answer:
175 m
Explanation:
Given:
v₀ = 2.4 m/s
a = 0.6 m/s²
t = 20.5 s
Unknown:
Δx
Equation:
Δx = v₀ t + ½ at²
Sub and solve:
Δx = (2.4 m/s) (20.5 s) + ½ (0.6 m/s²) (20.5 s)²
Δx ≈ 175 m
