Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

Consider a spacecraft orbiting Earth. At an instant in time, the angular velocity of the spacecraft
relative to Earth is = 1.361+0.90b2+0.33b3 (in rad/s). Now consider a top spinning in the
spacecraft with an angular velocity relative to the spacecraft of wr = 8.9b1 +0.15b2+0.14b3 (in
rad/s). What is the magnitude of the angular velocity (in rad/s) of the spinning top relative to the
Earth reference frame.
Note b1, b2, bz are unit vectors fixed in the spacecraft reference frame.

A theodolite is an instrument that measures horizontal and vertical angular orientations of a line of sight. The line of sight may be established optically, or by laser, and many forms of theodolite are used in surveying, construction, astronomy, and manufacturing. A simple optical theodolite is shown. After the instrument is aligned so that its base is in a horizontal plane and a desired reference direction is selected (such as perhaps north in the case of a surveying instrument), the telescopic sight is used to establish a line of sight, and then horizontal and vertical angles Thetah and Thetav are measured. If Thetah = 30° and and Thetav = 60°, determine the following: 7.1 The coordinate direction angle Alpha of the line of sight is Blank 1°. 7.2 The coordinate direction angle Beta of the line of sight is Blank 2°. 7.3 The coordinate direction angle Gamma of the line of sight is Blank 3°.
