Answer:
Kindly check explanation
Step-by-step explanation:
Think of inelastic Collison as a phenomenon whereby the colluding bodies do not rebound. That is the direction of motion of the two bodies after collision is in a single direction, moving with a single final velocity as opposed to bodies moving in different directions with differing final velocities after collision during an elastic collision. Therefore, the final kinetic energy during an inelastic Collison isn't conserved.
Mathematically,
Inelastic Collison can be written has :
m1u1 + m2u2 = v(m1 + m2)
Whereby ;
m1, m2 are masses of the first and second colliding objects
u1 and u2 are their initial velocities
Note that, we only have a single final velocity, v, which shows that the colliding objects move in the same direction after collision.
Let x be the large number, and y be the smaller one: x=3+2y, 2x-5y=0 (from the question) --> substitute the first equation in the second --> 2(3+2y)-5y=0 --> 6+4y-5y=0 -->6-y=0 --> y=6, substitute y=6 in the first equation --> x=3+2(6) --> x=15. therefore the two numbers are 6,15

In the given question, it is already disclosed that the typing speed of Finke has increased from 40 words per minute to 45 words per minute. Now we have to find the percentage increase in the speed of typing.
For this purpose we have to find the solution in the method described below.
Number of increase in words typed per minute = 45 -40
= 5
Then Percentage increase in the speed of typing by Finke = (5/40) * 100
= (1/8) * 100
= 25/2
= 12.5
So the percentage increase in the typing speed of Finke is 12.5%. I hope this has answered your question and the description used to solve this problem is understandable.
