hard, search on internet as I don't know this
Answer:
use desmo's graphing calculator that might help
Step-by-step explanation:
I don't know the answer but use this to graph
the final speed in m/s of the 10.0 kg is 2.53 m/s .
<u>Step-by-step explanation:</u>
Here we have , A 10.0 kg and a 2.0 kg cart approach each other on a horizontal friction less air track. Their total kinetic energy before collision is 96 ). Assume their collision is elastic. We need to find What is the final speed in m/s of the 10.0 kg mass if that of the 2.0 kg mass is 8.0 m/s . Let's find out:
We know that in an elastic collision :
⇒ Total kinetic energy before collision = Total kinetic energy after collision
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , the final speed in m/s of the 10.0 kg is 2.53 m/s .
Answer:
The answer would be 48 If im not mistaking
Answer:
24 1/5
Step-by-step explanation:
First you add 12 2/5 + 11 4/5 and that leaves you with 23 6/5 simplify it into <u>24 1/5 </u>and you get your answer!
