Momentum Theory Use one-dimensional conservation of momentum together with conservation of mass (continuity) and energy (Bernoulli’s equation = mechanical energy) to derive the power an ideal, frictionless wind turbine with an infinite number of blades, uniform thrust over the rotor area and a non-rotating wake can extract from the wind. Formulate the derivation in terms of the fractional decrease in wind velocity between the velocity far upstream and at the turbine rotor, ? = (? − ?)/?, also called “axial...

4. Consider two asteroids with masses mi and m2 located in outer space far away from any external forces. m2 is initially stationary but mi travels horizontally to the right towards m2 with an initial speed vo. Let's assume that after the collision the asteroids only move horizontally (in other words we'll assume this problem is purely 1-dimensional) a) Suppose the asteroids stick together after colliding. Find an expression for the final velocity of the asteroids and show that the...

Suppose that we repeat the experiment in the video but use
hand-held weights of different masses and different initial speeds.
In each of the cases below, the demonstrator starts with her arms
extended (rotating at angular speed ?0) and then pulls her
arms in (rotating at angular speed ?f). Rank the cases
below based on their final angular speed ?f (that is, when
the demonstrator’s arms are pulled in), from slowest to fastest.
Since most of the mass of the...
