Homework Statement
An athlete executing a long jump leaves the ground at a 29.5∘ angle and travels 7.69m . A- What was the take off speed? B- If this speed were increased by just 4.0%, how much longer would the jump be?
Well, if you had searched the net for SUVAT, as I suggested, you might well have found this, for example: http://en.wikipedia.org/wiki/Equations_of_motion.Superstar said:I'm sorry, but I have no idea what that means. I just started Physics for the first time a few days ago, and am having a very hard time
The distance of a long jump is measured from the take-off point to the nearest mark made in the sand by any part of the athlete's body.
The 29.5" mark indicates the height at which the athlete left the ground during the long jump. This height is used to calculate the athlete's vertical velocity and trajectory, which can be used to analyze their performance.
The take-off angle, or the angle at which the athlete leaves the ground, can greatly impact their long jump distance. A more optimal angle can result in a longer jump, while a less optimal angle can result in a shorter jump.
An athlete's strength, speed, technique, and body mechanics can all play a role in their ability to jump and reach the 29.5" mark in a long jump. Training and conditioning in these areas can help improve an athlete's performance.
Scientists can analyze data from a long jump, such as take-off angle, velocity, and distance, to study an athlete's performance and identify areas for improvement. This data can also be compared to other athletes to gain insights and inform training programs.
