Model
<span>
When making a guess and retesting this information, a
theory or <u>model</u> may be formed which explains why something has occurred
or what it may look like. Models are a representation of a certain situations
that has occurred. These models can provide and amplify a clearer perception
and comprehension of how and what processes are involved in an occurred
phenomenon. And by that said, it can change and be modified depending on which factor
catalyzed the alterations. </span>
Answer:
Velocity of the 24.6 g marble is 31 cm/s.
Step-by-step explanation:
Given:
Marble 1:
Mass of the marble 
= 12.3 gm
Velocity of 
before collision 
= 15.5 cm/s
Velocity of after collision 
= 77.5 cm/s
Marble 2:
Mass of the marble 
= 24.6 gm
Velocity of 
before collision 
= 62 cm/s
Velocity of after collision 
= ?
From the law of conservation of momentum, we know that momentum before equals the momentum after :
So,
⇒ 
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
⇒ 
⇒ 
...subtracting both sides 953.25
⇒ 
⇒ 
...dividing both sides with 24.6
⇒ 
⇒ 
cm/s
The velocity of the 24.6 g marble after the collision is 31 cm/s and it will move opposite to of the 12.3 g marbles that is towards left.
Answer:
Yes
Step-by-step explanation:
I'm assuming this is right
I believe the answer is A because you cannot find x nor y
