A model airplane of mass 0.750 kg flies in a horizontal circle at the end of a 60.0 m control wire, with a speed of 35.0 m/s. Compute the tension in the wire if it makes a constant angle of 20.0° with the horizontal. The forces exerted on the airplane are the pull of the control wire, the gravitational force, and aerodynamic lift, which acts at 20.0° inward from the vertical.

A block of mass m=2.20 kg slides down a 30 degree incline which is 3.60 m high. At the bottom, it strikes a block of mass=7.00 kg which is at rest on a horizontal surface in the picture. If the collision is elastic, and friction can be ignored, determine (a)the speeds of the two blocks after the collision, and (b) how far back up the incline the smaller mass will go.

Let x and y be real numbers such that

\frac{\sin x}{\sin y} = 3

\frac{\cos x}{\cos y} = \frac{1}{2}

\frac{\sin 2 x}{\sin 2 y} + \frac{\cos 2 x}{\cos 2 y}

can be expressed in the form

\frac{p}{q}

, where p and q are relatively ' positive integers. Find p+q.

Characteristic function of logarithm of random variable
If I know the characteristic function

ϕ_{X} (t)

of a random variable

X > 0

, how can I write the characteristic function

ϕ_{Y} (t)

Y = \log (X)

ϕ_{X} (t) = E [e^{i t X}]

ϕ_{Y} (t) = E [e^{i t \log (X)}]

. But I can't derive one from the other. Any idea? I would like to use

ϕ_{X} (t)

to calculate the second moments

Suppose a cable car moves with direction vector

\vec{d}

(\begin{matrix} 2 \\ - 2 \\ 1 \end{matrix})

The question asks, "at what angle to the horizontal does the cable car travel?". By horizontal, if you assume the x-axis, the angle can be found using

\frac{| \vec{a} \cdot \vec{b} |}{| \vec{a} \vec{b} |}

) Using this, the angle I find between

\vec{d}

(\begin{matrix} 2 \\ 0 \\ 0 \end{matrix})

The angle I find is

{48.2}^{\circ}

. If I use the z-vector instead:

(\begin{matrix} 0 \\ 0 \\ 1 \end{matrix})

The angle I find is

{70.5}^{\circ}

\approx {19.5}^{\circ}

. How would I get this value?

Find all triangles with a fixed base and opposite angle
I have a situation where I know the cartesian coordinates of the 2 vertices of a triangle that form its base, hence I know the length of the base and this is fixed.
I also know the angle opposite the base and this is also fixed.
Now what I want to do is figure out how to compute all possible positions for the third vertex.
My maths is rusty, I reverted to drawing lots of pictures and with the help of some tracing paper I believe that the set of all possible vertices that satisfies the fixed base and opposite angle prescribes a circle or possibly some sort of ellipse, my drawings are too rough to discern which.
I started with a simple case of an equilateral triangle, with a base length of two, i.e. the 3rd vertex is directly above the x origin, 0, base runs from -1 to 1 along the x-axis
then i started drawing other triangles that had that same base, -1 to 1 and the same opposite angle of 60 degrees or pi/3 depending on your taste
now i need to take it to the next step and compute the x and y coordinates for all possible positions of that opposite vertex.
struggling with the maths, do i use the sin rule, i.e. sin a /

= \sin b / B

and so on, or do I need to break it down into right angle triangles and then just use something along the lines of

a^{2} + b^{2} = c^{2}

ultimately, I intend to plot the line that represents all the possible vertex positions but i have to figure out the mathematical relationship between that and the facts, namely,
base is fixed running from (-1,0) to (1,0) angle opposite the base is 60 deg
I then need to extend to arbitrary bases and opposite angles, but thought starting with a nice simple one might be a good stepping stone.
