Answer:
0.34 sec
Explanation:
Low point of spring ( length of stretched spring ) = 5.8 cm
midpoint of spring = 5.8 / 2 = 2.9 cm
Determine the oscillation period
at equilibrum condition
Kx = Mg
g= 9.8 m/s^2
x = 2.9 * 10^-2 m
k / m = 9.8 / ( 2.9 * 10^-2 ) = 337.93
note : w =
=
= 18.38 rad/sec
Period of oscillation = ![2\pi / w](https://tex.z-dn.net/?f=2%5Cpi%20%20%2F%20w)
= 0.34 sec
Power is defined as the rate at which the body is doing work:
![P=\frac{W}{t}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BW%7D%7Bt%7D)
Work is defined as displacement done by the force times that displacement:
![W=F\cdot h](https://tex.z-dn.net/?f=W%3DF%5Ccdot%20h)
We know that we need 62N to move the box, so when we apply this force along the path of 10m we have done:
![W=62N\cdot10m=620J](https://tex.z-dn.net/?f=W%3D62N%5Ccdot10m%3D620J)
of work.
Now we just divide that by 5s to get how much power is required:
Answer:
![\ d_{out} = 100 \ m.](https://tex.z-dn.net/?f=%5C%20d_%7Bout%7D%20%3D%20100%20%5C%20m.)
Explanation:
Given data:
![F_{in} = 50 \ \rm N](https://tex.z-dn.net/?f=F_%7Bin%7D%20%3D%2050%20%5C%20%5Crm%20N)
![F_{out} = 10 \ \rm N](https://tex.z-dn.net/?f=F_%7Bout%7D%20%3D%2010%20%5C%20%5Crm%20N)
![d_{in} = 20 \ m](https://tex.z-dn.net/?f=d_%7Bin%7D%20%3D%2020%20%5C%20m)
Let the distance traveled by the object in the second case be ![d_{out}.](https://tex.z-dn.net/?f=d_%7Bout%7D.)
In the given problem, work done by the forces are same in both the cases.
Thus,
![W_{in} = W_{out}](https://tex.z-dn.net/?f=W_%7Bin%7D%20%3D%20W_%7Bout%7D)
![F_{in}.d_{in} = F_{out}.d_{out}](https://tex.z-dn.net/?f=F_%7Bin%7D.d_%7Bin%7D%20%3D%20F_%7Bout%7D.d_%7Bout%7D)
![\Rightarrow \ d_{out} = \frac{F_{in}.d_{in}}{F_{out}}](https://tex.z-dn.net/?f=%5CRightarrow%20%5C%20d_%7Bout%7D%20%3D%20%5Cfrac%7BF_%7Bin%7D.d_%7Bin%7D%7D%7BF_%7Bout%7D%7D)
![\ d_{out} = \frac{50 \times 20}{10}](https://tex.z-dn.net/?f=%5C%20d_%7Bout%7D%20%3D%20%5Cfrac%7B50%20%5Ctimes%2020%7D%7B10%7D)
![\ d_{out} = 100 \ m.](https://tex.z-dn.net/?f=%5C%20d_%7Bout%7D%20%3D%20100%20%5C%20m.)
