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>
Answer:
Option E
The planning and construction of the resorts represent an impact lag of this policy.
Explanation:
Whereas the legislation was enacted without any delay but planning takes six months and construction taking 2 months, it means the policy has a lag. Therefore, option E, the planning and construction of the resorts represent an impact lag of this policy.
Answer:
17.799°
Explanation:
When the bullet hits the block at that time the momentum is conserved
So, initial momentum = final momentum
![P_i=P_f](https://tex.z-dn.net/?f=P_i%3DP_f)
So ![28\times 10^{-3}\times 210=(3.6+0.028)v_f](https://tex.z-dn.net/?f=28%5Ctimes%2010%5E%7B-3%7D%5Ctimes%20210%3D%283.6%2B0.028%29v_f)
![v_f=1.6207\ m/sec](https://tex.z-dn.net/?f=v_f%3D1.6207%5C%20m%2Fsec)
Now energy is also conserved
So ![\frac{1}{2}\times (3.6+0.028)\times 1.6207^2=(3.6+0.028)\times 9.81\times 2.8(1-cos\Theta )](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%283.6%2B0.028%29%5Ctimes%201.6207%5E2%3D%283.6%2B0.028%29%5Ctimes%209.81%5Ctimes%202.8%281-cos%5CTheta%20%29)
![cos\Theta =0.8521So\ \Theta =17.799^{\circ}](https://tex.z-dn.net/?f=cos%5CTheta%20%3D0.8521So%5C%20%5CTheta%20%3D17.799%5E%7B%5Ccirc%7D)
Answer:
The design-limiting property that insufficiently large is the elastic modulus (Young modulus)
Explanation:
Plastic usually have a relatively low elastic modulus, this couses the material to deform too much under stress. In the case of a bicycle, a little weight you put on it or little bumps will cause the bicycle to deform too much.
A question the design team should answer before handing off the designs is: are the designs a true representation of the intended end user experience?
<h3>What is a website?</h3>
A website can be defined as a collective name that is used to describe series of webpages that are interconnected or linked together with the same domain name.
In Computer technology, the main goal of a high-fidelity prototype is to understand how end users would interact with a website and areas to improve the design.
In conclusion, the design team should answer whether or not the designs are a true representation of the intended end user experience before handing off the designs.
