Document Summary

Lecture 1 - introduction to sport and exercise. The study of the effect of psychological and emotional factors on sport and exercise performance, and the effect of sport and exercise involvement on psychological and emotional factors. Psychological factors can have an effect on sport and exercise, but sport and exercise can also have an effect on psychological factors. Ancient greeks (200 ad: gold standard for optimizing athletic performance . Day 4: relaxation: even in ancient greece, they were conscious that to be a successful athlete it was important to train the mind and give it time to rest. Conducted the first piece of research regarding exercise psychology. Noticed cyclists went faster when cycling together than alone. Performance is impacted by the presence of others . Created a university course based on sport psych. Worked as a consultant with athletic teams. Sport psych and motor development: dorothy hazeltine yates. One of the first women in the field.

One of the new events in the 2002 Winter Olympics was the sport ofskeleton (see photo). Starting at the top of a steep, icy track, arider jumps onto a sled (known as a skeleton) and proceeds-bellydown and head first-to slide down the track. The track has fifteenturns and drops 101 m in elevation from top to bottom.
(a) In the absence of nonconservative forces, such as friction andair resistance, what would be the speed of a rider at the bottom ofthe track? Assume that the speed of the rider at the beginning ofthe run is relatively small and can be ignored.
1 m/s

(b) In reality, the best riders reach the bottom with a speed of35.8 m/s (about 80 mi/h). How much work is done on an 84.1-kg riderand skeleton by nonconservative forces?

The sport of skateboarding provides an excellent example of theprinciple of Conservation of Energy. In particular, let us consider'vert skateboarding' where a person rides the skateboard on avertical ramp that forms part of a hemisphere referred to as a'half-pipe.' It consists of the transition from the curved part tothe flat and the vertical. Below is a schematic of a half-pipe withthe 'vert'. The surface of the half-pipe and the material of thewheels on the skateboard allow for an almost frictionless ride.Therefore we will neglect friction in the following analysis.

The rider starts from rest at location 1 at the edge of the in-rampand goes down the transition. Typically, as the rider approachesthe flat at location 2 he will crouch down to get his center ofmass as low as possible and thus increase his speed. To simplifythe problem, let us initially assume that the rider stays uprightas he goes down so that his center of mass location relative to hisfeet does not change from what it was at location 1 . In thefollowing problems, you can use the foot as the unit length insteadof meters. Note: g = 32 ft/s2.

Estimate the maximum speed a rider might have at location 2

(b) For the speed you estimated in part (a), using Conservation ofEnergy, determine the maximum height the rider can rise up to as hegoes up the vert.

24.4 - Cathode-ray-tube oscilloscopes have parallel metal plates inside them to deflect the electron beam. These plates are called the deflecting plates. Typically, they are squares 3.0 cm on a side and separated by 5.0 mm, with vacuum in between. What is the capacitance of these deflecting plates and hence of the oscil- loscope? (Note: This capacitance can sometimes have an effect on the circuit you are trying to study and must be taken into consider- ation in your calculations.)
