One of the most well known track and field events is the long jump. This event is where an athlete sprints as fast as they can toward a line then jump into a sand pit. Several simple kinematic concepts are displayed in this event. Firstly the distance traveled by an object is proportional to the velocity of an object. This translates to the long jump in that the faster the person is moving as they approach the point where they have to jump, the farther they will travel. Also the length of the jump will be determined by the angle the jumper makes with respect to the ground. The ideal angle for this is 45 degrees, because this produces an ideal balance between velocity going in the x-direction and the y-direction. Therefore any good long jumper will have both good spped as they approach their jump as well as the skill to propel themselves at a 45 degree angle to the ground in order to produce the maximal distance out of their jump.
