Ok? is this a question or what?
Answer: for ideal situation
T2 = 16.5158K
Work = - 11.4J
For appropriate generalization correlation
T2 = 308.57K
Work = 177.797MJ
Explanation:detailed calculation and explanation is shown in the image below.
Answer:
Speed=1.633 m/s
Force= 20 N
Explanation:
Ideally,
hence
where v is the speed of collar, m is the mass of collar, k is spring constant and s is the displacement.
In this case, s=100-0=100mm=0.1m since 1 m is equivalent to 1000mm
k is given as 200 N/m and mass is 0.75 Kg
Substituting the given values
![v=0.1 m\sqrt \frac {200 N/m}{0.75 Kg}=1.632993162 m/s\approx 1.633 m/s](https://tex.z-dn.net/?f=v%3D0.1%20m%5Csqrt%20%5Cfrac%20%7B200%20N%2Fm%7D%7B0.75%20Kg%7D%3D1.632993162%20m%2Fs%5Capprox%201.633%20m%2Fs)
Therefore, <u>the speed is 1.633 m/s</u>
The sum of vertical forces is given by mg where g is acceleration due to gravity and it's value taken as ![9.81 m/s^{2}](https://tex.z-dn.net/?f=9.81%20m%2Fs%5E%7B2%7D)
Therefore, ![F_y=0.75\times 9.81=7.3575 N\approx 7.36 N](https://tex.z-dn.net/?f=F_y%3D0.75%5Ctimes%209.81%3D7.3575%20N%5Capprox%207.36%20N)
The sum of forces in normal direction is given by
therefore
![Ma_n=200*0.1=20 N](https://tex.z-dn.net/?f=Ma_n%3D200%2A0.1%3D20%20N)
Therefore, <u>normal force on the rod is 20 N</u>
