The value of constant in terms of Force, k, A, V and ρ is x = ln (F /kAρV ).
<h3>What is opposing force?</h3>
The force which tends to oppose motion of fluid in forward direction like shear stress in liquids and friction force in solids
A body moving through the air at speed V, experiences the retarding force.
Force = kAρVˣ
where A is the surface area, ρ is the density of air and k is the numerical constant.
Taking natural logarithm both sides,
ln F = ln (kAρVˣ)
ln F = x ln (kAρV)
x = ln F / ln (kAρV)
x= ln (F /kAρV )
x= ln F - ln (kAρV)
Thus, the value of constant is deduced in terms of Force , k, A, V and ρ.

Answer:
The final speed of puck 1 is 0.739 m/s towards west and puck 2 is 2.02 m/s towards east .
Explanation:
Let us consider east as positive direction and west as negative direction .
Given
mass of puck 1 , 
mass of puck 2 , 
initial speed of puck 1 , 
initial speed of puck 2 , 
Final speed of puck 1 and puck 2 be
respectively
Apply conservation of linear momentum

=>
=>
-----(A)
Since collision is perfectly elastic , coefficient restitution e=1

=>
------(B)
From equation (A) and (B)

and 
Thus the final speed of puck 1 is 0.739 m/s towards west and puck 2 is 2.02 m/s towards east .
Answer:
is it 20kg. Two opposing forces pushing onto each other
Answer:
A
Explanation:
Kinetic energy must be moving. Potential energy has the ability to move but is not doing so at the moment.
A is likely the answer. But there's lots involved in that kind of motion.
B If the ball is elevated, it implies it is not moving yet. It has potential energy.
C Again, the spring is compressed. It will push something when it moves, but it is not moving yet.
D The load gun's bullet is not moving. It's still potential energy.
E. The mouse trap is set, but it is not moving. When the mouse eats the bait then it's potential energy will transform into kinetic energy.
