The three strata of study within the study of kinesiology are:
1. Core scientific domain: the core scientific domain deals with the sub disciplines that are found in kinesiology. Examples of these sub disciplines are biomechanics, sport medicine, exercise physiology, history of sport and dance, neurophysiology of performance, physiology of sport, sociology of sport, etc.
2. Sociocultural based form of movement: this aspect of kinesiology deals with the different types of games, sport and dance that are practised in different cultures and countries. The aspect studies expert skills that are involved in different sociocultural based movements. Examples of sociocultural based movements are aquatics, combative, individual sport, running, etc.
3. Methods in professional application: these deals with the professional training and careers that are available in kinesiology. There are generally five areas of professional training, they are: capacity building, management and administration, performance enhancement, instruction in physical education and research.
Answer:
3.69 m/s
Explanation:
Forces :
mgsin Θ - mumgcosΘ = ma
g x sinΘ - mu x g x cosΘ = a
9.8 x sin 21 - 0.53 x 9.8 x cos 21 = a
a = -1.337 m/s²
so you have final velocity = 0 m/s
initial velocity = ? m/s
Given d = 5.1 m
By kinematics
vf² = vo² + 2ad
0 = vo² + 2 x -1.337*5.1
vo = 3.69 m/s
None of the energy is created nor destroyed
Answer:
Explanation:
Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.
The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:
Substitute the values into the formula.
Multiply.
- 1 kilogram meter per square second is equal to 1 Newton.
- Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.
The force required is <u>252.5 Newtons</u>.
