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 $\frac{\mathrm{sin}x}{\mathrm{sin}y}=3$ and $\frac{\mathrm{cos}x}{\mathrm{cos}y}=\frac{1}{2}$ . The value of $\frac{\mathrm{sin}2x}{\mathrm{sin}2y}+\frac{\mathrm{cos}2x}{\mathrm{cos}2y}$ can be expressed in the form $\frac{p}{q}$ , where p and q are relatively ' positive integers. Find p+q.

$M=1+{\displaystyle \frac{a}{b}}$

$S=a+b$

So, I put it up like this:

$1+{\displaystyle \frac{a}{b}}=a+b$

If $M=S$, how to isolate $a$?
