Answer:
<em>a) P(21)=40</em>
<em>b) P max = 60</em>
<em>c) P min = 20</em>
Explanation:
<u>Function Modeling</u>
The blood pressure P is modeled with the equation
Where t is in seconds.
a) We'll find the pressure when t=21 seconds
b) The maximum value will occur when the sine function has a value of 1
c) The minimum pressure will occur when the sine function is at minimum (-1)
Answer:
a = 0.1 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
Vf = final velocity = 0.8 [m/s]
Vo = initial velocity = 0.3 [m/s]
a = acceleration [m/s²]
t = time = 5 [s]
![0.8=0.3+a*t\\0.5 = 5*a\\a = 0.1 [m/s^{2}]](https://tex.z-dn.net/?f=0.8%3D0.3%2Ba%2At%5C%5C0.5%20%3D%205%2Aa%5C%5Ca%20%3D%200.1%20%5Bm%2Fs%5E%7B2%7D%5D)
Distance = speed * time, then time = distance / speed.
time = 50 / 0.4 = 125 s
A movement which keeps the distal end of the body segment fixed in one location describes what type of kinetic chain movement is known as a <u>closed kinetic chain movement.</u>
<h3>What is a closed kinetic chain movement?</h3>
A closed kinetic chain movement is defined as that position where the most distal aspects of a particular extremity are fixed to the earth or another solid object.
In conclusion; a movement which keeps the distal end of the body segment fixed in one location describes what type of kinetic chain movement is known as a closed kinetic chain movement.
