ROTATIONAL KINEMATICS‚ MOMENT OF INERTIA | 1. A child is pushing a merry-go-round. The angle through the merry-go-round has turned varies with time according to θ(t) = γt + βt3‚ where γ = 0.400 rad/s and β = 0.0120 rad/s3. a. Calculate the angular acceleration as a function of time. b. What is the initial value of the angular velocity? c. Calculate the instantaneous value of the angular velocity at t =5.00 s and the average angular velocity for the time interval t = 0 to t = 5.00 s. 2. At t

1 CHAPTER 3 PLANE AND SPHERICAL TRIGONOMETRY 3.1 Introduction It is assumed in this chapter that readers are familiar with the usual elementary formulas encountered in introductory trigonometry. We start the chapter with a brief review of the solution of a plane triangle. While most of this will be familiar to readers‚ it is suggested that it be not skipped over entirely‚ because the examples in it contain some cautionary notes concerning hidden pitfalls. This is followed by a quick review of spherical

M1 SUVAT Equations 1. An aircraft moves along a straight horizontal runway with constant acceleration. It passes a point A on the runway with speed 16 m s–1. It then passes the point B on the runway with speed 34 m s–1. The distance from A to B is 150 m. (a) Find the acceleration of the aircraft. (3) (b) Find the time taken by the aircraft in moving from A to B. (2) (c) Find‚ to 3 significant figures‚ the speed of the aircraft when it passes the point mid-way between A and B. (2) (Total

The Vector equation of a plane To find the vector equation of a plane a point on the plane and two different direction vectors are required. The equation is defined as: where a is the point on the plane and b and c are the vectors. This equation can then be written as: The Cartesian equation of a plane The cartesian equation of the plane is easier to use. The equation is defined as: One of the advantages to writing the equation in cartesian form is that we can easily find the normal

and many comedies. One comedy he wrote was the play Measure for Measure. It can be argued that because of the deep gloom and moral concerns underlying this play‚ Measure for Measure can be considered a problem play. Many questions are raised in the play about justice and mortality and these questions also lead the reader to think why the play was named Measure for Measure and not something else. There are many ways the title Measure for Measure‚ by William Shakespeare‚ can be interpreted such as:

Here is another example: Imagine you are flying over the ocean in an airplane‚ when you suddenly think about what would happen if one part of the plane were to fail. The plane would crash. You then cheer up by a single thought; this plane over the course of many years was tested and designed. You trust in the builders‚ because your airplane could not made by chance‚

and transformations have been used for hundreds of year by various composers to create different styles of music. This method of making music is done on a musical plane and its dimensions are pitch space and time. Symmetry and transformations can be seen on both a smaller scale‚ when a measure is repeated upside down in the next measure and a larger scale where entire pieces are played forward and backward simultaneously in a crab canon or in a table canon where the notes are upside down as well as
