Math 273 ? Lab 1 ? F 07 Curve Balls and Vectors Does a baseball pitch really curve or is it some sort of optical illusion? Assume the pitcher's mound is at the point (60, 0, 0) and that home plate is at the origin of our coordinate system. Suppose the pitcher throws the ball toward home plate and gives it a spin of s revolutions per second about a vertical axis through the center of the ball. This spin is described by the spin vector s where s points along the axis of revolution with length s. From aerodynamics we learn that this spin causes a difference in air pressure on the sides of the ball and results in a spin acceleration on the ball given by , where c is some empirical constant and is the velocity vector. The total acceleration of the ball is then ,

9/30/2018 Entropy: Why Life Always Seems to Get More Complicated https://jamesclear.com/entropy 1/11 JAMES CLEAR Entropy: Why Life Always Seems to Get More Complicated by James Clear (staging.jamesclear.com/about)????| ???? Mental Models (https://jamesclear.com/mental-models) Murphy's Law states, ?Anything that can go wrong, will go wrong.? This pithy statement references the annoying tendency of life to cause trouble and make things difficult. Problems seem to arise naturally on their own, while solutions always require our attention, energy, and effort. Life never seems to just work itself out for us. If anything, our lives become more complicated and gradually decline into disorder rather than remaining simple and structured. Why is that?

4.1 Simple harmonic motion 1a. [4 marks] This question is about simple harmonic motion (SHM). The graph shows the variation with time of the acceleration of an object X undergoing simple harmonic motion (SHM). Determine the maximum displacement of X. Give your answer to an appropriate number of significant figures. Markscheme use of ; or or ; } (allow answers in the range of T = 7.8 to 8.0 (s) or = 0.785 to 0.805 (rad s)) ; (allow answers in the range of 4.0 to 4.25 (m)) two significant figures in final answer whatever the value; Award [4] for a bald correct answer. Examiners report Similarly, this was well done. Most appreciated the need to truncate the final answer to a sensible number of significant digits (two in this case). 1b. [2 marks]

What force does the air in the tire apply to the spring? 10.1 The Ideal Spring and Simple Harmonic Motion 10.1 The Ideal Spring and Simple Harmonic Motion Conceptual Example 2 Are Shorter Springs Stiffer? A 10-coil spring has a spring constant k. If the spring is cut in half, so there are two 5-coil springs, what is the spring constant of each of the smaller springs? 10.1 The Ideal Spring and Simple Harmonic Motion HOOKE?S LAW: RESTORING FORCE OF AN IDEAL SPRING
