The work done by along the given path <em>C</em> from <em>A</em> to <em>B</em> is given by the line integral,
I assume the path itself is a line segment, which can be parameterized by
with 0 ≤ <em>t</em> ≤ 1. Then the work performed by <em>F</em> along <em>C</em> is
Answer:
Γ = r x F vector notation for torque
Doubling r (the length) will double the torque applied
Answer:
magnitude v0x = v0 * cos θ = 31 m/s * cos 16° = 30 m/s
Explanation:
Please see the figure for a graphical description of the problem. As you can see from the figure, the vector v0 (initial velocity) is the sum of its horizontal and vertical components v0x + v0y.
Using the trigonometric rule for right triangles:
cos θ = adjacent / hypotenuse
We can calculate the magnitude of the v0x vector.
Seeing the figure, notice that the vectors v0, its horizontal component, v0x, and its vertical component, v0y, form a right triangle.
v0x is the side adjacent to the angle θ, and v0 is the hypotenuse of the triangle. Then:
cos θ = magnitude v0x / magnitude v0
magnitude v0x = magnitude v0 * cos θ = 31 m/s * cos 16° = 30 m/s

Answer:
Ficus trees are warm-weather, tropical trees. Varieties include the fruit-producing fig, the houseplant Ficus benjamina, and the rubber plant. Whether you grow ficus trees in the landscape or in the home, providing the right temperature is vital to prevent damage and ensure good, healthy growth on the tree.
