After the second car starts out,
D = 30 + 110 H
360 = 30 + 110 H
330 = 110 H
H = 330/110
H = 3 hours after the second car leaves.
That's 3.5 hours after the first car leaves.
The answer is A, transporting nutrients
Answer:
0.43
Explanation:
Sum of forces in the y direction:
∑F = ma
N − mg = 0
N = mg
There are friction forces in two directions: centripetal and tangential. The centripetal acceleration is:
ac = v² / r
ac = (35 m/s)² / 564 m
ac = 2.17 m/s²
The total acceleration is:
a = √(ac² + at²)
a = √((2.17 m/s²)² + (3.62 m/s²)²)
a = 4.22 m/s²
Sum of forces:
∑F = ma
Nμ = ma
mgμ = ma
μ = a / g
μ = 4.22 m/s² / 9.8 m/s²
μ = 0.43
