Volleyball Serve Biomechanical factors influencing my Performance Contacting the ball at the top of arms reach If I did not contact the ball at the top of arms reach I would loose acceleration because the force is greater when the arm is at full reach. By contacting the ball at full arms reach you are creating a longer leaver and increasing the moment of inertia by increasing the force upon which you can accelerate the arm forward to serve the ball. If the ball contacted beyond the top

Mock AIME Series Thomas Mildorf November 24‚ 2005 The following are five problem sets designed to be used for preparation for the American Invitation Math Exam. Part of my philosophy is that one should train by working problems that are more difficult than one is likely to encounter‚ so I have made these mock contests extremely difficult. The idea is that‚ once you become acclimated to them‚ the real AIMEs will seem easier‚ and you will approach them with justifiable confidence. Therefore‚ do not

As some of my peers might know‚ geometry is definitely not my favorite subject in math. I have always struggled with geometry‚ especially with memorizing formulas to solve problems such as finding volume‚ surface area and more. I always found formulas to be such a bother and even after learning one and mastering it somewhat‚ I usually ended up forgetting the formula. Fortunately‚ the formulas that I had the most trouble with‚ being volume‚ surface area‚ and area‚ have finally began to stick with

Cartesian coordinates‚ also called rectangular coordinates‚ provide a method of rendering graphs and indicating the positions of points on a two-dimensional surface or in three-dimensional space. The scheme gets its name from one of the first people known to have used it‚ the French mathematician and philosopher René Descartes. The Cartesian coordinates in the plane are specified in terms of the x -coordinates axis and the y -coordinate axis‚ as illustrated in the below figure. The origin is the
