Answer:
a) 20 feet per year
b) 44.1 m
Step-by-step explanation:
Given:
Distance traveled during the observation period = 55.3 meters
Observation period = 9 years
initial velocity of v₀ = 11 m/s
friction coefficient of stone on ice is μ = 0.14
g = 9.81 m/s²
also,
v₀² = 2μgS
Now,
1 m = 3.28084 ft
thus,
Total distance in feet = 55.3 × 3.28084 = 181.430452 ft
Average speed =
or
Average speed =
or
Average speed = 20.159 feet/year ≈ 20 feet per year
b) v₀² = 2μgS
substituting the values in the above equation, we get
11² = 2 × 0.14 × 9.81 × s
or
121 = 2.7468 × s
or
s = 44.051 ≈ 44.1 m
Answer:
Step-by-step explanation:
When naming lines, you can use the label of the line, in this case, m, and can also name the points in either direction, since the line goes on forever in both directions (it's different with rays). The leaves only line B as an answer.
The vertex of XYZ would be Y, since the vertex is always the middle number.
was the amount of his withdrawal, w, if his ending balance was $922.
O 982 - w = 922
O W - 982 = 922
O 922 - W = 982
Answer:
Try 60
Step-by-step explanation:
982-922=60
