Answer:
the diver's speed is independent of the launch height.
Explanation:
For this exercise we must use Newton's second law
               fr - W = m a
the friction force has the general form
               fr = b v
Let's analyze this equation to find out what happens with the speed of the distant club.
When jumping, the initial speed is zero, so the friction force is zero and has an acceleration equal to the acceleration of gravity, as the speed increases the friction force increases decreasing the acceleration until it becomes zero, when it arrives at this value the velocity it has is called terminal velocity and this velocity remains fixed in relation to the trajectory.
              fr = W
              v = cte
The distance or time in which this equilibrium is reached is relatively fast, so the diver's speed is independent of the launch height.
 
        
             
        
        
        
Answer:
(I UNDERLINED AND MADE ITALIC THE MOST IMPORTANT INFORMATION) <em><u>A vocation is an occupation to which a person is especially drawn or for which they are suited, trained, or qualified. Though now often used in non-Latin vocātiō 'a call, summons')religious contexts, the meanings of the term originated in Christianity.  (from </u></em>
Explanation:
<em><u>A call, summons, or impulsion to perform a certain function or enter a certain career, esp. a religious one. Vocation is defined as a call to do something, especially regarding religious work.</u></em> The woman's desire to become a nun is an example of vocation.<u><em> a strong impulse or inclination to follow a particular activity or career</em></u>.<em><u> a divine call to God's service or to the Christian life. a function or station in life to which one is called by God</u></em>: the religious vocation; the vocation of marriage. <u><em>There are many different types of vocations in today's society. The three significant vocations are, single life, married life, and religious life. </em></u>Single life is one of the three types of vocation. <u><em>Definition of Vocation and Career: Vocation is what you strive to do in your life. It is the career you want to be in. Career, on the other hand, is a series of jobs, even change of professions, in a lifetime of an individual. Vocation is literally your "calling", what you are good for or destined for. It usually is a property/talent/predisposition of your person. A mission, in contrast, is a particular task given to you. Even if you are on "a mission from God", there may be retirement from it eventually.</em></u>

The relative uncertainty in the dimensions of the cylinders will be the same.
<h3>Volume of each cylinder</h3>
The volume of each cylinder is determined by applying the following formula.
V = πr²h
The volume of each cylinder will be the same since the diameter and length was measured with the same precision.
<h3>Relative uncertainty</h3>
The relative uncertainty in the measurement is the error associated with the measurement of the dimensions of the cylinder.
Thus, the relative uncertainty in the dimensions of the cylinders will be the same.

Answer:
Momentum = 1.534 kgm/s
Explanation:
Using the equations of motion, we can obtain the velocity of the ball as it hits the ground.
g = 9.8 m/s²
y = 12 m
u = initial velocity = 0 m/s, since the ball was released from rest
v = final velocity befor the ball hits the ground.
v² = u² + 2ay
v² = 0 + 2×9.8×12 = 235.2
v = 15.34 m/s
The momentum at any point is given as mass × velocity at that point
Mass = 100 g = 0.1 kg, velocity = 15.34 m/s
Momentum = 0.1 × 15.34 = 1.534 kgm/s
